    # Dom's idea to try and rework the ubersystem menu system so we can append things to it from plugins
    # right now, we can't really inject things into the menu from plugins, and I thought this should be an easier thing.
    # (mostly, was trying to get some links for the band plugin on the main menu)
    #
    # TLDR ended up coming up with this idea for how to represent the menu in python, and then passing that as JSON to
    # our javascript code which actually creates the HTML elements.
    #
    # Lemme know what you guys think and if it's worth pursuing I'll continue on with this when I have a few spare minutes
