There's a lot of mods, especially custom scripts and things, that often require you to add an app to your display in order to configure it. Others require an app (sometimes invisible) just to even function properly. And some apps try to have built-in settings configurations, but it's often wonky and half the time might not even save between sessions. I propose a new tab in the game settings that's dedicated to mod configuration. Any mods or apps you have installed that are configurable, modders can add support to their mod so that it shows up there.
