There is danger of me introducing bugs in the frontend, and you finding
them :). This would however be useful to QA the frontend.
The way you can do it, is simply keep pulling (or merging) from my
branch into your branch. Bzr makes this really easy.

Hum, I think you shouldn't. I think you should sub-class it. As a general
rule, having to copy something is the sign of bad software design. If you
find yourself having to copy, I would be happy if you tell me, as this
might be the sign of a design mistake on my side.

No. However, I am open to suggestions if you find design fault in the
frontend. I will not add code taylored to specific needs, subclasses are
ment for this, but we may find that the way things that are impossible to
do by subclassing, and this may reveal design faults.

Yes. Thank you. I have fixed that.

IMHO, this is a feature. Well, not exactly: the fact that the drop-down
menu still pops up after pressing tab is not great, but it is the only
way I have found yet to keep the drop-down menu up. That drop down menu
is really nice, I love it, and I still want it. It should just disappear
when the tab key is pressed, and come back when needed. The problem is
finding the right heuristic for "when needed". I agree that this still
could use some more work.
