well, yeah, that's what i do sometimes.. definitely not a single click process though.. and even then, i don't do it as often as i should.. seems like i usually end up resorting to the toolbar because stopping to set up a shortcut kills the workflow.. thing is, i'm often left trying to find the icon on the toolbar etc..
i dunno, it's just an idea that i'm throwing out there.. i'm not expecting someone to actually write this thing π
