Build me a small Java client with a simple in game style GUI that lets me manage a set of togglable features from one screen.

I want the GUI to open with right shift by default, and the command prefix to be a dot by default, with both of those changeable later from commands or a config file. Include a command system for things like toggling features, binding keys, saving and loading settings, changing the prefix, switching config folders for different servers, and marking friends or enemies so they show up differently in the player list. Also add a way to show a selected feature on an array list, and let me customize the message text used for the built in taunt style message if that mode is enabled.

Make it feel polished and easy to use, with settings that can be saved manually and loaded back later. If you need to look up current docs online for anything, go ahead.
