Description

When an event recurrence happens (makes sense when recurring from completion date especially), i'd like the possibility to clone the task, so the old task is not destroyed, and stays in my done bucket.

Hey! @kolaente I'd like to work on this feature. My plan is to add a new repeat mode that clones the task on completion instead of updating the dates in-place, leaving the completed task in history. Before I start coding, wanted to check if you have any preference on the approach or things I should keep in mind. Thanks!

@Mateus-Sousa93 great! The approach sounds like it could work, but it should be a flag on the reminder, not a repeating mode. And we need to figure out where the reminder lives, if we'll only duplicate the task, we'll have many copies of the task with a duplicating reminder each very fast. Maybe use relations for the connection?

@Mateus-Sousa93 As someone migrating from Microsoft ToDo, have you made any progress here? Can I assist you here?
