the alpha-elements minecraft launcher manager, built using python
To run, you need to install Python 3.x and download the dcgf graphics library. Extract its files either to your python package path or into <.minecraft directory>/alpha_elements.
AlphaElements is a launcher for the default Minecraft Launcher. It automatically installs the modded Minecraft Forge client and the performance and tweak mod OptiFine. In AlphaElements you can import other mods and enable or disable them to your needs in different versions. When you're done, just launch the Minecraft Launcher using the Play button.
Thx to @CatfifikatorHD for the base idea and some help!
