I remember when i was browsing app store on “things 3”, one of Agenda’s competitor, they offer progress indicator lika fan shape progress indicator, it looks nice and my efficiency would be intensified by it. hope this feature can be updated.
For Agenda it wouldn’t be trivial to add. Starting with at what level you would want such an indicator, for each note within a project or for the project as a whole. Technically the latter is not easy to do I’m afraid.
