A nice feature would be a level MX number under the level number for items that boost other things ever X levels such as the Supernova Forge which boosts the maximum Magnetic Cooling every 50 levels [In case you didn't understand what I meant by MX I used M as short for Modulo] so you can see how many more of them you need to get until the next boost
*nod* yeah once you hit one k plus you can no longer see the actual value you a rounded value for the tens place and nothing for the ones place and for most things that doesn't matter but when you get special power ups for ever x levels it becomes nice knowing how close you are to that next power up
