Thanks for this great plugin, again.
Couple of feature requests/suggestions:
1) would it be possible to extend it to present 'capabilities' options/drop down selectors on
a) admin, posts, category, edit category screens, also
b) on any screen showing edit screens for custom categories - (as many plugins uses them for content). this feature would make the plugin truly amazing.
otherwise i'll have to code it up/hack it in myself somehow.
2) would it be possible to have it render 'capabilities' drop down selectors agsainst :
a) edit/select theme screens,
b) edit/select (active) plugin screens
b) edit/select (active) sidebar widgets screens
- that way it will become possible to implement capabilities on eg: members of groups being able to see output from particular plugins, have particular widgets available, etc.
note: the plygin s2members framework pretty much approaches these things (via its hook/filter api set, etc) - but your plugin is more straight forward/better aliogned with wp core i think.
again, things i'll ultimately need to code up myself otherwise.
thanks for any thought/feedback
