There can be more than Notion and Miro

Do you have a list of integrations, both working and planned? How well does it play with markdown? What is the format of the drawings? Am I blind or is there no info on the database system? My biggest problem with notion is its reminder system - if you change the time of a scheduled item, the reminder is removed, even though it was originally defined relative to event time and should thus be easy to recompute. Or do you not have schedule/calendar system?
