it is meant to do something else -- make the item as small as its minimum
size allows -- at least IIRC and it would be consistent with how weights
work in other layouts.
Yes, Ingo is bang-on here.
> I'm not sure why a view can't be expanded with the mouse after hiding
it. That does indeed seem to be a bug. Or maybe it is actually not
supposed to be done like this (I don't recall). Then a dedicated interface
is needed -- `BSplitView::SetCollapsed()`. I would be nice to have that
anyway as it would be clearer for the API user.
I agree, a dedicated interface would be the best option. Hide()ing a view
shouldn't have the same effect as collapsing it, IMO, since
collapse/expand behaviour is controlled by the BSplitView.

Yes, I can do that :)
