instead of having to option + tab to pull up the spaces window, having an assigned keyboard short cut (like option+1, option+2, etc.,) for each space would be helpful - much like switching between tabs in chrome (currently cmd+1,2,3, etc.). Could possibly be an ascending default value (1,2,3) or have a custom shortcut like option+h for 'home' space or option+w for 'work' space.
