I'm using BTT to show Mission Control desktop preview which is missing in El Capitan. I'm having a problem with snapping windows though. If I snap a window to half my screen, how do I get it back to the way I had it? Right now I have to manually resize it which is a pain. I also have HyperDock and it's much easier to snap in and out with keyboard commands. So I'm using both BTT and HD, but I wanted to have only one tool running on my system.
