I know this topic has to be on the tips of a lot of users' tongues. From a previous thread over at NewsGator I understand that there is some kind of an Apple framework for you to add WYSIWYG?
Right now one of the difficulties I have when drafting in ME is that creating an ordered or unordered list is very very involved. So involved that I essentially make the list in the WP admin and paste it back into ME.
I really don't care if it's an embedded WYSIWYG with live editable previews but it would be nice if formatting with the various standard tags could be made easier via GUI.
