Installation:
1. Copy the downloaded zip file into your Data Folder, if you have steam that should be something like: "C:ProgrammeSteamsteamappscommonskyrimData"
2. Unzip the archive directly into that file(The interface folder contained in the archive should be in the Data folder)
3. ???
4. PROFIT! (Well that should be it)


Uninstall:
Simply remove the files it added to your Data folder, that would be "DataInterfacecraftingmenu.swf" and "DataInterfaceinventory componentsinventorylist.swf" and it should be normal again, for security I would rather rename them in case it doesn't work and you want to revert it again.
