This looks useful.
A couple of quick comments.
The 'Help' button should be on the toolbar. There are many things we want
to do that aren't intuitive, at least the first time you use them, and will
remain unintuitive no matter how well designed the interface.
Also, if we make significant changes to the interface now, 1.0 will be
undocumented. Us docs people don't have time to rewrite everything in the
apparent 1.0 timeframe. As it stands, we should have the interface
documented, in XHTML, in time. Minor changes might be doable, though.
