[Suggestion]Time bar can be used in Full Screen Mode

It would be great if I can use reset,run, run speed adjust in full screen mode

There are shortcut keys to do the job.
You can find them in the manual under Main Menu and Toolbar / Execute Menu or directly in the Execute Menu.
Are they not enough?

Another way could be to have a Model Control GUI to do the job.
Have a look in my Sample Models, where I use such a GUI.
This GUI stays on top if you switch to Full Screen Mode.
