Hi
I see that path allready but thats not a real deal. You dont want to use 10 different launcher for 1 game
Thats why minecraft has now its own launcher, or i think that was the idea.
Forge will go also the same very nice way with the new forge versions. Its a little script part to change a directory. But you must know where it is
Any forge user can create a folder with a special name. So that will be not a problem.
Greetings
