Make mods easily makeable

I think you should be able to make mods in the game kind of how you create characters. You can make your own custom stuff, play your mod, and you can do multiplayer and be able to submit it to Mojang to maybe have it put in the marketplace. And while in the game making mods, it is easy you don't have to do programming and stuff. It would be easy because you can choose stuff to do like there would be things like make new items or make new mobs and stuff and you press on it and choose if you want to add it to a mod you have made or a new mod
