I've seen requests to include distinguishing between tasks and events as well as to check out completed tasks in Google Calendar and I'd also appreciate having these features. As far as I understand, all tasks appear in Google Calendar as events because Google Calendar API only provides opportunity to add events, judging from what I've seen. Maybe it would help to have Google Tasks integration as it is integrated in Google Calendar and would give possibility to check out completed tasks there without having to delete them completely and at the same time separate them from events? In my opinion, it would be at least better to have tasks from Taskade appear in Google Calendar as tasks instead of events as Taskade is mainly concentrated on task management.
