Rated 3 out of 5 stars

After I installed this add-on, I experienced, it makes no sense to install it on a Mac, because all it does is to put a Windows titlebar right underneath the systems own titlebar - looks funny in deed, but is useless!
On a Mac it is buggy too, downsizing from fullscreen (which is exactly the same like regular Mac fullscreen - I mean no more space than usual), it kicks several buttons on all toolbars out of the window frame - toolbars don't fit into it!

So please provide the info here, it is not for Mac OS! Thanks
