Yes, I understand your view, which I concur with.

I have done some work in this area fairly recently, to tidy up the UI.
As the changes were not trivial, were in an area where I hadn't worked
previously, and were completed too close to the release date of the new
stable version to allow adequate testing by others, I've held them back.

Once the new release has gone ahead, my patches will be reviewed and,
hopefully, added to the svn version, when you may see how they meet
your concerns (or otherwise).
