In projects in which we have a lot of notes per deliverable, it quickly becomes unhandy to understand which notes belong to which activity. So it would be great to be able to either sort by activity on the notes tab of the details overlay or group notes in a better way. If you have an activity-oriented view onto your project, this is what you are interested in which goes into the direction of an activity timeline eventually. But for the start, users should be able to understand the connection faster.
