Hello,
it would be cool to be able to differentiate between different releases in the view where you can uninstall - if you want to keep just the latest version of Unity from each release and have a few installed already, it gets kinda hard to go through the list.
I think that either color coding the releases, e.g., all 2018.1 to have the same color, and all 2017.4 to have the same color as well (but different than 2018.1), or grouping it based on a release (with the list being sorted from newest to latest in each respective group) with a heading showing the version (just the 2018.1/2017.4/etc. part), would help tremendously.
