Visualize disk usage of each version

Tell us how we can improve Xcodes
When keeping several Xcode versions installed in parallel with multiple platform downloads included, the disk space consumption can quickly get out of hand on your machine. It would be great if Xcodes could help manage disk space consumption.

Is your feature request related to a problem? Please describe.
I'm regularly running into disk space issues and need to scan my folders on what can be ditched, e.g. using Finder and Disk Inventory X. From within Xcodes I need to flip through each installed versions and check size and platform installs.

What would you like to see? How would you like it to work?
I'd love to see a disk space usage number in the list of Xcodes, together with disk space available. Ideally this is visualized using a graphical representation, e.g. like disk space utility, making it easy to spot big consumption.

The issue names no source files, tests, or entry points. Start by locating the installed-Xcode list and the app's storage-related code; done means each installed version shows its disk usage, available disk space is shown, and the information has a graphical visualization.
