Dear Baratorchik,
often we have the opportunity to play not only at home but also at work. Here however we are not alone in most cases.
Will be welcome to implement hot key combinations that would make the game completely disappear from the screen but would continue to run in background. Respectively different/same combination would bring the game back on the screen.
Thanks in advance
P. S. If anyone would like this feature, please support the idea. For a small number of people probably isn't worth to do it, but if demand is high ... who knows, best!
