It would be great to be able to organise files in into collections similar to how Adobe Photoshop Lightroom works. Basically have one copy of a file and be able to include/index that file in several different collections. For example I have a design file that was part of a university project. At the moment I have one copy of the file in my 'University Projects' folder and 1 copy in my 'Portfolio' folder. I would rather have 1 copy of the file and be able to add the file to a collection called 'University Projects' and a collection called 'Portfolio'. I would be able to access the file by navigating to either collection. If I update the file through one collection, the updates would also show in the other collection.
