Good day. I understand we are talking about the hotkey functions? In my opinion this is a pretty good idea, only with the ability to save and load would still be able to rewind the game. And even better would be to give the ability to disable each function separately. For example, if you disable any function, assign an empty value for this combination in the configuration file. And it would be nice somewhere(for example to make a section in the menu - help) to list all the functionality of the hotkey button.
P.S. I apologize if sloppy wrote. I use online translator
