Ability to move a file to a non-existing group without having to create that group first

For example, pressing "ctl-shif-2" should move the file to group 2 whether that group exists or not. In addition, when a group has no files (views) at all it should disappear. That way we don't have create and remove groups when needed and no longer needed. This will save a lot of time and hassle.

What you do guys think?
