I would love the ability to sync my Intercom availability with my Google Calendar so that it automatically takes me out of rotation (Away) for assignment when I mark myself OOO in Google Calendar.
Optionally, some folks might also want Away automatically set when they are busy in Google Calendar, but I also get that the needed syncing frequency could make that problematic to implement. (OOO feels more doable since that is less likely to change throughout the day, whereas individual calendar appointments frequently change in my experience.)
