I'm looking at a variety of new reader options, with out-of-the-box EPUB support being #1, so Kindle is out. Other than that, though, what I care most about is the ability to display a book correctly.

Currently, I have an Onyx Boox M92, and the best reader available for it is a fairly ancient version of Cool Reader, and even some basic HTML/CSS features are either not implemented at all (like borders and "height"), or are quite buggy (like "line-height" or "<br />" handling). So, I have to do a lot of editing of ebooks before they are readable on the M92, and I'd like to cut that time down.

In addition, though, there are some newer HTML/CSS features that I find really either make the book look a lot better (like "float" for initial caps, or OpenType small caps), or help make otherwise hard-to-create layouts easy (like background images), so I'd like to be able to use them if possible.

So, has anybody compiled (and maintained for current versions) any kind of HTML/CSS errata lists for both proprietary readers (like those built-in to Kobo devices) and ones that support multiple devices (like Android readers, etc.)?

For reader apps I can get for free to test (like most of the Android apps), I'll probably do my own testing anyway, but if somebody else has already started, that would make my work a bit easier.
