In testing 3.3.1 (beta) the [minimize] button does place the app in the system tray but it appears that you need to double click the app in the system tray to activate the window again. Is this the expected behavior? It seems inconsistent with other apps in the system tray that typically take a single click to reactivate.
Also a left click in the system tray provides on one option, [Exit] while a left click, when the app was on the task bar, provided a list of pinned, recent files and the option to close the app. Again is this the expected behavior?
