Yes, this is much better (and I have some more things to add at some
point).  Some things are in bugzilla, some of these maybe should be.

I was just kind of cautioning you against confusing the base texteditor
infrastucture with parsing/other related features that would likely be
agnostic to an editor.  For example, C# 2 support is irrelevent here but
easy access to the document structure for refactoring isn't (and
something I agree we need).

Ok, I was just trying to help you in gathering information while
recommending a course of action that is reasonable (i.e. where to look
archives & code).  Much of this was previously discussed in some detail
and some of us have already formed opinions on what is the best way to

Keep in mind it is just my opinion after all.
