I'm looking into porting the theme support from XEmacs into Emacs. However, looking at the 21.0 source there are also some features that could be ported the other way, like: Doc improvements. Using customize to set local variables New keyword :set-after (explicit dependencies between options) new font attributes Some of the later could perhaps be emulated with wmperry's font.el package (same way the current font attributes are handled). If I start working on these, will someone look at it?
