I'm not sure whether this feature is only good for me as a "heavy tester" , but...
Sometimes I have multiple Simulides running and forget one to pause, which then is taking performance of the PC in the background.
In order to find this Simulide instance, it would be great to have the state of the simulation already in the title (helps to find this instance on the taskbar).
The (already used) power icon, stop icon and pause icon might be easy to catch visually. Changing the title bars color would be also an alternative (IMHO this might get annoying when having the simulation in fullscreen, too).
