Yesterday I asked folks on Twitter what improvements they wanted to see to
CSS. The most common responses were to have ebook reading systems support
more of the CSS that browsers do.

The other major theme was about how ebook reading systems override the CSS
in EPUB files. This process is totally opaque to ebook developers, very
frustrating for all involved, and results in unpredictable end results.
Shining some light on this process, providing a way for developers to
respond to various types of overrides, and giving end users the control
they need would be of immense value. I think this should be a priority of
DPUB, perhaps even a task force.

Many of the other suggestions related to typography--better control over
hyphenation, open type font features such as ligatures, and drop caps.

I've added priorities to the spreadsheet[1], and sorted by those
priorities. In general, specs exist for most of the features listed, but
browser support is often spotty. In many cases, some major browsers support
a given feature, and other major browsers don't. And that is our
fundamental issue.

[1] yes, all my priorities are wrong.
