Stacked quickButtons instead of horizontal scroll: thoughts?

[luddilo]

For applications that utilize a lot of quickButtons the current design with a horizontal scroll might not be ideal. I was thinking that a vertically stacked option would make sense, with a setting to toggle these two designs.

Is this functionality easily available? Is someone already working on it or should I take a stab at it? Any pointers for where to start?

How it looks with a horizontal scroll:

How it could look stacked (this is by just changing the white-space CSS property of the .quick-buttons-container div. Not a complete solution in itself since it does increase the height of the widget):

If someone wants to help with making it more pretty, I would be grateful :-)
