Dumy folders for categorizaton

On the web front I would like to sort actual folders into categories for easyer visualization rather than having 50 columns all displayed at once the folders would be inside another dropdown, would it be possible to implement?

It would, and there is a ticket for this already, but nobody cares enough about this to do the work. Feel free to implement this.
