hehe, I was thinking about making it movable/lockable first but decided that's too much afford for such a little button. (at the moment I'm sick, I have the flue and my headaches keep me from thinking)
After a lot of ranting and complaining at other UI-Sites, I decided to plaxe the button near the close button at the topright corner. May that be satisfying for all of you *sigh*
(Sometimes it's no fun developing addons).
Just add commandline options for x different positions *eg*
