Is it already possible that Minetest supports minetest.conf files specific to a particular world? All settings in such a file should overwrite settings of the “global” minetest.conf.
I know a similar thing already exists for subgames.
If it's not yet possible, I propose to add such a thing because I think this would be useful.
If implemented, the order or preference should be this (“>” = “overwrites”):
World-specific minetest.conf > Subgame-specific minetest.conf > Global minetest.conf > Default settings
I also propose to add the server command “setw”. It's the same as “set” the only difference is that it uses the world-specific minetest.conf (for the current world) instead.
Use case: I often tend to do “/set time_speed 0” on worlds where I just want to test stuff (this disables the movement of the sun), but I still want to have the normal behaviour for all other worlds for actual playing. Too bad this always changes the global time_speed which is annoying. With “/setw time_speed 0” I can set it for the current world only.
