[FR] Overlapping Timetables

[okg00dbye]

Not sure if this has been suggested before -

May be useful to support displaying overlapping timetables from multiple people to find out what are common free time slots to meet with each other. Similar to the "meet with" feature in Google Calendar (example)

I see that sharing timetables using URLs are already supported - we can add a feature that utilises this by allowing users to enter a list of timetable URLs, which will then update the UI to display all input timetables side-by-side.

If this makes sense I can offer to make the PR for it... :O
