A really good feature should be the 'collection' of files in one folder.

What I mean. Lets say that we have 3 folders with luxury cars. One folder BMW, 2nd Audi, 3rd Ferrari.

Each folder consists of images.

I would like to create a main folder with the name 'Luxury Cars' which will have the best images from these 3 folders. For now, we need to duplicate these images and upload them to this folder.

In other words, it would be good if 1 uploaded image is possible to be shared in two or three folders at the same time.
