1.add a better UI.Basiclly, copy the minecraft item UI EXACTLY as it is, because its the best.
2.add more body slots being able to get unlocked.The game wont let you use jetpack and parachute at the same time.
3.add the genius splitter.if you press E when you are hovering the genius spitter, it will open a menu where u can split items exactly how you want.The genius splitter will tell you how much items it recieves per minute and you will be able to set it with numbers, for example if you have 200,you can split it 60 left, 120 center, and 20 right OR you can set a percentage, for example 30% left, 50% center, and 20% right.It will be unlocked at tier 5.Done.
