Suggestion for a way to customize the way the large toolbar expand when clicking the chevron

It would be nice if there was a way to customize the way the toolbar expand when you click the chevron.

In Qt 3 when a toolbar was too small to display its controls it would
have a chevron to the right, and that would pop up a menu with the
missing buttons. In Qt 4, the entire toolbar slides out one ore more new
rows with the missing controls.

The problem we have is the following: if
only a few controls were missing the controls are left-justified, so you
have to move the mouse pointer all the way back to the left to click
something (see attached screencap, going from A to B). If you drift out
of the toolbar area (eg when using a trackpad on a laptop), the toolbar
collapses automatically.

It would be nice if the following points were accomodated for in Qt:

• reenable the old Qt 3 behavior (which seems easily doable from looking
  at the code, the functionality is just not exposed and limited to
  running on OSX in unified toolbar mode)

• right-justify the controls so they are closer to the initial click
  location

• have a optional timeout for the collapse, so it's more forgiving if
  you drift out
