Sometimes I have a project that is "locked" to a Unity version, for various reasons. Usually because some plugin has not been upgraded to any newer Unity version, or it's just working perfectly and I just don't want to bother upgrading and having to break/test/fix/upgrade anything else in it. Then when cleaning up installs, I delete some old Unity install that is need for some specific project. I suggest to display a little bubble on each install with the number of projects that uses it. By clicking that bubble, drop down a list of those projects (like the ... menu). Clicking on the project, open it on the Projects view. That would be super helpful. Thanks.
