Navigating with ALT-TAB is broken when you get in a tile group.
First I like the idea of tile groups, but ounce I swap to a window in a group using alt-tab, if I press alt-tab again, it does not come back to my last active window, but get trapped in a cycle between windows of the group, changing ALT-TAB behavior. To get out of this cycle, I must hold ALT and get to a window which is not part of the group. This is really annoying is there a way to keep Normal ALT-TAB behavior and let window snapping ? If there is not, I'd like to file a bug, but for which application ? For now I just disabled the tile groups completely.
