Went to read the manual and found nothing when it came to GUI's. (To be specific I am making an item that will show a GUI when right clicked.). I know this is a dumb question, but are GUI's supported on the newest version of the MDK? If so, where can I find a way to add them? If GUI support isn't allowed, can I just use J Frames instead?
