Config Manager.

IStonia,
I have just an idea of Config Manager. Some kind of window that will allow to manage differend configurations, Load/Save and Change.
So for example I have 2 configuration Dark and Light and this window will allow me to change between them.
Also it will allow to change between config made by different users.

I do not know if NVil can update all that settings without restart, so it is just conception of possible greate feature.

May be at least color scheme and UI manager?
It will include Colors, Grid settings and UI(windows).

I do not know how it works so I just generate an ideas.
