Some bad merge with your global removal?

Not sure I like relying on the default 0,0 position - position doesn't seem to me like something that has a natural default for an absolutely positioned actor - the fact that you are positioning at the upper left of the group and 0,0 owrks is more an accident of screen layout then something inherent.

Actually the button should be under the bottom of the last workspace as in:

We want to leave room for the message tray at the bottom of the screen I think.
