FJ,
I will try not to derail your thread. Definitely +1

But.... Would it be nicer if we had a floating, non modal /dockable to toolbar set Quick Buttons that you can assign virtually any shortcut command as Ctrl+F8?
I think a great place for that is the cluster to the left of transport (New, Save As, etc.). So you can replace existing button(s), with other button(s) of your choice.
