Easy Config Button
Ever see that Mod Options button in the world pause menu, then click it only to realize it does nothing, was never finished and is completely useless?
Well, now it isn't! With this mod installed, the button will now lead to the Mod List GUI normally only accessible from the Main Menu, allowing you to change configs without leaving your world, allowing for easier and more convenient testing and debugging of config options. (as long as they don't require a world or minecraft restart)
A very small tweak mod, but very useful for modders and modpack creators testing and debugging.
For a small overview, look no further than here!
