Axel Dörfler, OpenTracker's maintainer, would like everyone's opinion on a new feature he is working on: If, let's say, you have folder A and folder B, both showing (their contents) in Tracker windows. You want to create a link (or move, or copy) folder A to folder B, you right-click and drag the little icon into folder B, no need to go to the parent folder of A and then drag it.
