not just like in optifine or sodium, but a mod that has the ability to have shaders applied via presets
e.g: i have a pvp preset with keystrokes and the cps mod, and i join a SMP thats more relaxed, so i could switch to a preset with a shader already loaded
it could also have an "advanced" mode, where you could write shaders in game with realtime updating
