Feature Request Project count per Editor version

I'd like to see how many projects are using every installed Editor version. So I could navigate to a filtered project list by slicking on that count and see if I really need that version, or I can get rid of those/upgrade and dump this version.

I find it hard to figure out what versions I can uninstall to free some space on my SSD. I frequently delete wrong verion and either need to reinstall it, or upgrade that project and find out that it was broken and I didn't keep it's version history. For me this is a really important feature. And I bet many developers that are trying to stay on a bleeding edge would agree.

That filtered project list would be another feature... Sorry.
