Really nice Add-on.
Just two suggestions for improvement...
So there is a Password function to lock the whole Speed Dial panel, but there isn't a function to just lock some of the categorys/groups (upper left corner). It would be great, if you could add this function.
The other point is that there isn't the possibility to freely determine the positions structure of the dial-windows. F.e. you want a "O" structure so all the dial-windows are at the edges but not in the middle.
