My workflow is like Open 1 app per 1 workspace. I set the most critical applications from which I sometimes copy something or need to place them next to each other in one workspace to open in neighboring workspaces. The rest are keyboard shortcuts to juggle between workspaces. I hardly use alt-tab
how did you change shortcuts? i'm trying to set a custome one for 'move active window left' but in settings there isn't an option for that. if i try to set a custom shortcut wher command = default and then shortcut = what i want, it doest work
