Pro Stays out of the way
While still allowing for insane customization.
Cons
Con Does not support the border of multiple displays well
When using multiple displays, the ability to dock a window to half of a display only works on one side of the screen divide. It can work (with some very careful cursor placement) only on the external monitor and not dividing edge of the native (laptop) monitor. It does not support quarter-splits either.
Bottom line, this was a great initial app, adding this capability before anyone else did, but it has been eclipsed by newer apps.
