At home i have a MacBook and for that a licence of OS X's famous CSSEdit.
In that editor i really like the feature, that you can group selectors or identifiers in your .css-files, using comments or comments with some special notation.
I think that would be great for WeBuilder aswell, as i think many people group their css-stuff into some userdefined groups, with those grouping features in CSSEdit, you have always a great overview where your groups are. An option for turning that behaviour on and off would be nice, too, for those who don't like that feature.
See the screenshot to see what i mean:

(btw. i know that "size" doesn't make sense there, i was intended to write font-size, but it was very late yesterday!
