Only other alternative menu is the Blockland Hub, which lets you use a build as your menu, with specified events that bring up GUI and stuff like that, personally I do not however find that too practical due to the amount of time taken to reach a button, if you decide to make it like a house, rather than making a menu which is even more pointless since the default is still easier.
But anyway, the only menu desktop theme for Blockland is BlockOS, and since it's not a real OS for competition, I don't think there's any reason for one to make a new... desktop theme; eventually something else, but not that.
