Allow updating and removing old versions of Unity

It would be nice to have Unity Hub tell me that there's a new version available (with something like the little green arrow), and allow me to update and remove the old version

 

Just for the record, I don't agree with this feature request and here is my argument:

Switching versions under a project is always dangerous and should not be taken lightly. Having the effort to make a backup, go to the releases, download the new version, remove the old one allow people to remember to actually make a backup.
The one-click solution will lead more unconsciously updated projects with consequences lead to more work and more frustration. (Update now with a big fat red warning window with the 'are you sure' and 'make a backup and come back' may work, but basically defeats the entire thing)

 

I think it could be useful having just some kind of indicator of new versions available.
As for the auto-remove, I agree with LurkingNinjaDev. And it wouldn't save you much time anyway.
