Thanks for this :-). Yes, it is a "micro-ugliness", but many of these
combined also contribute to some kind of "uncomfortable" feeling after a
while; usability should not be underestimated.

It works better now, but - well, not perfect still. Folders are not
collapsed any more after a D&D operation, but what is now awkward is what
happens if you add e.g. Track 1 of a MIDI file to one Qtractor track, and
attempt to just D&D Track 2 into another Qtractor track. This doesn't work
because the previous track did not get unselected after the first D&D, so
you are now attempting to D&D 2 tracks at the same time (kind of "multi-select"
I guess). It can worked around by additional clicks to unselect everything,
but that's trading one ugliness for another :-).

That's perhaps the reason why you only commented that one line in the source
code instead of removing it right away.
I believe what should happen here instead of the "QTreeWidget::reset();"
is something like "un-select all items in the widget" (no idea what that's 
called in Qt speech).
