Yes, that was interesting.  The animation was much better, no longer
jerky.  Probably because the motion is blurred slightly by the drop
shadow.  Without the drop shadow the hard outline is much more obvious
as it shifts position during the animation.

Yes, I like that, much easier to comprehend.  Without such a hint, the
frame arrival violates physics.  See screenshot of frame over journal,

Agreed, it looked good.

It also increased the speed of switching between windows.  It was
especially obvious when toggling between the journal (F4) and the home
view (F3).  (Not at all obvious when switching between F1, F2, and F3
views, but that's because these are not implemented as window switching;
the redraw is done by Sugar shell.  Perhaps they should be separare
windows instead.)
