Vertical Toolbar for Extension Buttons

Or, as a alternative, the ability to drag buttons to the panel (which when showing has a lot of available vertical space). Currently, if you try to drag a button to the panel, it looks like it is permitted (it's not crossed out like when you drag it somewhere else forbidden), but it doesn't stick there when you release it.
Seems minor, but this is the biggest thing I miss from Firefox.
