I don't understand where you would need it except in the tree.
In fact it would be nice there. Now +/- just reloads the entire page, 
which is not reasonable.

Instead of

<a href="alt_db_navframe.php?PM=0_1_1_browsePages#0_1" name="0_1"><img 
src="../typo3conf/ext/skin_grey/icons/gfx/ol/plus.gif" width="18" 
height="16" alt="" /></a>

Corresponding JavaScript could be reasonable.
