Solves the problem, but rough around edges
I like the way this is trying to solve the problem of focusing my attention on only the existing task. However, it has some problems. I use ⌘-tab a lot and it just feels weird because for a split second, the old in-focus window is still highlighted. This feels jarring.
I have disabled HazeOver, but leave startup-at-login enabled. Every time I reboot, HazeOver re-enables itself, which is super annoying. I finally decided to remove it, but there is no way to quit the app. At all. Once it starts, its always running. Ive even gone into the preferences window and selected "Quit" from the menu bar. No dice.
Like I said, neat app to solve a problem I have. Not quite working for me, so Im not using it anymore, but it might work well for you. Certainly worth $2 to find out. Even though it doesnt fit my needs, I would have given a higher rating if the UX was smoother.
