You can glitch the game by going between High and Low graphics at the right time, I've currently got 3.1 million DPS. It is showing 2 Jumpers with over 600k each.
In the lists of things that I own in the create menu or the crafting menu, I think I'd prefer to see only what I have got usable, so not seeing loads of things I have used already with 'x0' next to them.
