Possible to save screen resolution settings and quickly switch between them?
I'm not 100% sure this is what you're after, but it's possible to check the "Show displays in menu bar" option in System Preferences -> Displays. This adds a menubar item which allows you to quickly switch between recently used resolutions



Alternatively, maybe something like Display Maestro or SwitchResX would help? These both seem to have the ability to display and switch between recently used resolutions.
