A main Menu Button

[Freeasabird🕊]

A Small request but, could we get a main menu button? i find it rather annoying that i have to shut my game down when i want to start a new world, "bad placement of my "Evo tower" er whatever, one of my Nuggets dies and i could of prevented it (getting use to the game still) or i just want to start over becuase reasons. my only option is quit the game or switch to i think Creative mode or something, whitch is something i don't want to do, i want to start over, not go creative.
