it would be helpful to have categories or folders inside the workspaces. Perhaps right click inside, and create a folder, then right click on an element and send to a folder?
Perhaps the folders could work as one of the following:
- Clicking on a folder could open a list, such as the one from "Add new mod element"
- Clicking on a folder could open a new window
- Clicking on a folder could change the workspace screen to that folder
