[Feature] Option to keep tasks in not-finished state until manually marked

[pravorskyi]

Hello!

Right now tasks and planned events in the app get marked as completed automatically.

It would be beneficial to introduce an option in the app settings to keep tasks in a not-finished state until manually marked as completed. This feature would create what I like to call "floating tasks," allowing users to maintain better control over their task management and ensuring that nothing is marked as completed prematurely.

It will increased control over task management and enables more accurate progress tracking.

I absolutely agree with this. Automatic task completion assumes that every planned task is always achieved. It's much more useful to manually tick off tasks as they are completed.

A useful addition would be, if the start time for a task has passed and the task hasn't been marked as completed, to change the colour or display a visual indication alerting the user to this. I often need to postpone a planned activity or I get distracted and seeing a warning of this in the task list helps me get back on track when things don't go to plan.
