Almost all the Git commits of Koodo have the same message: "fix bug". https://github.com/koodo-reader/koodo-reader/commits/master/

I'm really not confortable with projects that treat the Git history as junk, to the point I'd rather avoid that software. I daily use the e-reader Koreader, and sometimes Plato, and their source code and Git history are clear and documented (though I think Koreader's choice of Lua is poorly suited to the task). I could patch Koreader to my taste and send pull requests.

It might be the most awesome software in the world, but if I can't read the majority of bug reports, it's not something I can feel comfortable using.

(This is not a flaw in the software, this is a flaw in me: I don't know how to read -- I'm assuming it's Mandarin Chinese, but I can't even reliably tell that.)

If thats really such an issue, you can just get the browser to translate them for you?

Not to be rude, but if that's the case, and you're unwilling to use "random" translation tools like Google Translate, what is the point of this comment? Not everyone in the world speaks English. Do you want them to learn English and post bug reports in English for you?

You have dozens and dozens of translation tools at your disposal that take <10 seconds to solve that problem.

You want me to trust random translation tools on the internet for technical issues?

No.

For an E reader? Sure it's not some production tool.

I have tried nearly all the epub readers mentioned.

Koodo is now what I use, it renders the best for me, I feel like I'm reading a paper book, which is great to me, the fonts and theme are great.

Calibre's epub reader is painfully slow to start, and it does not look that good either.

I wish other epub readers can have better fonts and color.
