Single click rollup/unroll?

Currently we have the option to select what double-clicking the titlebar of a note does.  It would be really nice to be able to have a single-click on a title bar toggle the rolled-up status as well as selecting the note.

Or, maybe, a roll/unroll button in the title bar, that appears only on mouseover.

Well, never mind  , I figured out how to edit the skin to add a rollup/unroll button.
