Feedback on a few days of koreader use on a TouchLux 3
The application works rather well, I still have several difficulties on the following points:
- The ON/OFF button switches the reader to standby, (instead of on/off) and if I hold it down for a long time, then the reader restarts.
- If the reader remains in standby, book open, after a few minutes the reader stops and when I restart the reader, I do not find my book on the right page.
- The gesture to increase/decrease the intensity of light also sometimes changes the font size.
- How do I get out of the file manager and return to reading the current book?
- How to know what the latest nightly builds updates contain ?
- is there a possibility to automatically start Koreader when the reader starts up ?
I will probably have more questions later, for the moment thank you to the developers and thank you also for your answers

Best approach for koreader + reflow for journal paper reading?
I use Koreader with PDF reflow for reading research journal papers (it's truly wonderful), and very frequently need to jump between the main text and the references section at the back of the doc. That's a common use case for reading research pubs, and many folks still print journal PDFs because hardcopy works well for jumping back and forth.
Hyperlinks won't work for at least two reasons:
Given that, what's the best approach to jump back and forth in a document?
A few clunky approaches:

Thanks everyone!
Hyperlinks won't work for at least two reasons:
- PDF reflow uses bitmapped image content rather than text and hyperlinks
- Many PDFs simply don't have hyperlinks, especially older PDFs
Given that, what's the best approach to jump back and forth in a document?
A few clunky approaches:
- Sometimes I put a permanent bookmark at the references section, and a temporary bookmark in the text body. When done looking at a reference, I jump back to the temporary bookmark and delete it. This is pretty clunky as bookmarks are designed for very different use cases.
- Flipping mode is an alternative, but that too is pretty clunky for this purpose.
- Some PDFs have a TOC, which makes it easy to jump to the references section, but it's then clunky to navigate back to the page I was reading.
What's the best approach for this use case of reading research papers?
Thanks everyone!

Update koreader version
My Kobo aura one with Koreader says that the koreader update is not available in OTA. If I manually download the Koreader update to the PC and then replace the folder in the Kobo, are the reading statistics and the progress of the books lost?

What would prevent you from changing fonts on an epub?
I have an epub that, whenever I go to change the font, it doesn't change.
All the other epub change fonts just fine, but not this one. I can enlarge or make the font smaller, but not change it.
What is it about this epub that prevents this? Is there some lock somewhere or something different about it?

Way to create 'global default' style for all books?
Hi all - first post ever. Thanks for the forum.
I've been using KOReader for about a week now on my Kobo Aura One and am enjoying it. I've dug into the settings and even edited defaults.lua (to increase the margins, they were too small for me).
After opening my first book up I tweaked the settings (changed the font, margins, font kerning, and turned off embedded fonts), but once I opened a second book I noticed that everything that I'd changed had reverted back to the preset defaults.
So my question - is there a way to set a global default of my tweaked settings once without having to do it every time I open a book? Much thanks in advance. :)

Hide or put all the .sdr folders in one place
I organize my files by folders on my likebook mars. This would be perfect, if it wasn't for the fact that for each file an .sdr folder is formed on the same location. I've tried hiding them by adding a dot on the start of the file, but that just makes me lose the progress I had on the book.
Is there a way to stop the .sdr folders from cluttering my file system without having to delete them?

About MuPDF ePub renderer
Hi
I opened some ePubs using the MuPDF renderer. I employed the recent Frenzie patch which modifies the font-size to "50". This size fits globally and needs not to be changed for text display. Some days ago, with the latest OTA Koreader version, a new dpi setting for MuPDF font-size has been added.
The comments below do not pretend to be exhaustive but address some of the current points which could be improved.
Displaying text.
I would give it globally a 9 out of 10 mark. Most of the time, the display is very precise. The display is very pleasantly crisp and reacts well to boldness settings. Embedded fonts display is quite good.
I spotted some few defects.
1. No hyphenation (or I did not know how to make it work).
2. Mishandling of <br/> tags. These are displayed like empty paragraphs instead of linebreaks (the gap is much too wide). I tried to declare a value of 0.5em or 2px to br in CSS, but this was not taken into account.
3. Padding and blockquote properties seem to be ignored. If need be, user agent margin values provide a replacement for exemple for h2 titles.
Remark: to go well with MuPDF, your CSS font-size values should not be written in pixels but in em or % values.
Displaying images.
I would give it 5 out of 10. It is difficult to assess. It somewhat complements the Coolreader renderer. The main miss is that the MuPDF renderer does not seem to comply with relative values. At this time, MuPDF fails also to display svg wrappers (mostly used for covers). On the other hand, it can display real svg images while cre can't.
Raster images
Displayed to their original size. CSS relative values seem to be ignored. Pinching out expands the display to full page. This works consistently when the image is contained in its own page.
Pinching out may look a little haphazard when performed on the image. If this is so, do it on the adjacent full text page (which obliterates margins and fits text to page) and then come back to the image page. When the page contains just one line of text, the display can be frightening (just one letter page high...)
Boldness is better kept at minimum value when displaying an image.
Unhappily I did not find any way to improve the display of smaller images embedded within the text. They seem to be stuck to their original size, which can be disappointing.
svg images
Contrary to cre, MuPDF displays pure svg images. Relative values seem to be ignored. For now the display is much smaller than it should be.
Pinching out to expand the svg image works but provides a huge and useless display. This is due to the specificity of svg format which cannot work like raster. It's also tricky to trigger and looks like an hit and miss process.
Non displaying tables
Text from tables is displayed on a single column. Other columns are ignored.
Conclusion
Now, MuPDF can best be used for ePubs containing mostly text. We can also use it to display svg images. My first wishes would be to enable hyphenation and enable it to take into account relative values for images.

Koreader on Likebook Mars : landscape night mode rendering problems
Hi there, I got yesterday my new Likebook Mars and installed Koreader from the device built in "app store". It fails to render properly books in landscape + night mode. I don't have my ereader now, so i cannot say which version of Koreader was installed.
Problem described here : https://github.com/koreader/koreader/issues/4231
It seems that it happens also to another e-ink androids ...
Has anyone got a workaround for this?
Is this working in your e-ink android devices?

Status line text size
I have KoReader installed on a Kobo Glo. At the bottom of the page there is the mini status line with a number of options showing such as the number of pages left in the current chapter.
The text size of this line is very small and I have difficulty reading it. Is there any way of configuring the size of this line so that it is readable to my older eyes. I haven't been able to find an option in the menus but it could be there and I just can't work out where it is.

KoReader - fonts
I have KoReader (2018- 12) running on a Kobo Glo. When displaying an EPUB document which has paragraphs declared as :
font-family : serif
font-family : sans-serif
and
font-family : monospace
I'm getting confusing results.
I have embedded fonts turned ON, the document does not have any fonts embedded in it - I am relying on the above generic font declarations.
The document displays correctly on other EPUB readers but in KoReader both the serif and sans-serif paragraphs display using the font selected in KoReader's menu. However the monospace paragraph displays in monospace irrespective of the menu selection.
Effectively this means that it's all or nothing for san-serif either the whole document (apart from monospace) is in serif or sans-serif.
If it wasn't for the monospace stuff displaying correctly I would think that KoReader didn't respect font-families within the EPUB, however it does handle that case.
Is this a known issue or a design decision ?

Kobo battery?
I bought an older Kobo from one of the Goodwill auctions. I think the battery is failing - I have to charge it up more than once a week, even when not in use. Is there a way to replace the battery easily? Probably a mistaken purchase- I wanted a cheap reader that just used my Kobo library (400+ books unread). I don't mind the slow page turning, but it's really getting annoying to pick it up and it's always wanting to get a charge.
