[SUGGESTION] Add some kind of "I am alive" indicator

[Welcius]

I think it would be a good idea to add any kind of warning to the user that sysUpdater didn't get frozen on the start, like a letter on screen that changes between "" "I" "/" for example, just to know for sure that the system is responsive before trying to select an option.
