If you have several windows grouped together, there is no space to move the grouped window around:
There is neither space on the left nor right to grab it and move the window around, so I always have to increase the window size until I have some space on the right.
Would be awesome to have a (tiny) fixed space on the left/right (maybe both) where you can move the window around.
