Show a roll-up of all member calendars in a tab
There should be a way to add a tab showing a summary of all the members availability.
It could show free/busy information in the same format as when we schedule a meeting. If details are shared with me, show them. Otherwise, limit the display to the status.
Doing that would free us of having to add time off/vacations in both personal and shared calendar.
This is even more helpful when we have multiple calendars for teams; projects; committes...
It could also follow channel membership when it becomes available.
