Add an option to disable limited movements range for units

It's a feature that I still don't appreciate very much: I read here (#18) that you won't that the option "Slay rules" make this game exactly as Slay and I perfectly understand that, but I really enjoy if you could add a new option, different from the "Slay rules" one, that let players enable this "new" different gameplay feature.

There is also another nuance: those 'possible movement' areas are rendered separately from other stuff and their rendering is actually quite expensive. Bigger zone - more negative influence on fps. So in later stages of the game it will everything into lagfest which I don't really want.

When you click on a region the game already show all of it surrounded by a withe line, so any kind of fps drops should already happen. I also don't think that any cpu (mobile or not) of the last 10 years can in difficult to to such operations. Anyway, another option it's to disable the "possible movements" screen (or add an option to disable it)
