How in your workflow would minimize-to-tray be helpful? I'm having some difficulty understanding, sorry.

To close the window to free up the desktop and still have it handy available in the tray, have the projects available as a context menu via RMB like the unity's hub.

It would be nice if you could right-click the task tray icon to see a list that allows you to launch registered projects at once.
This is a feature found in UnityHub.
