If possible, one more position...

I just discovered this add on for firefox and I like it very much: thank you!

If I may, I have a little suggestion: besides all possible positions which one can choose, I miss the following one

Menu toolbar -> Last (flushed right)

At present, it is only possible to choose “Menu toolbar -> Last”, which only places the add on just after the last menu item (i.e. “Help”).

Is this feasible?
