I've noticed that for Samus, the little icons under her portrait that show what items she has are the same for her Missiles and her Missile Expansion. Both are Missile Tanks, so when you get both you will have two Missile Tank icons next to each other. I had a small idea: What if the icon for Missiles was just a missile without a tank, and the icon for the Missile Expansion was the Missile Tank? I think having separate icons would be more informative and look nicer, plus it fits with the game because you get Missiles from a Missile pickup left by an enemy or block, but you get the Expansion by collecting the Missile Tank power-up from a ?-Box. Implementing this would just be a matter of erasing the tank from one of the icons on Samus' template. EDIT: Actually it looks like all the Samus sheets already have Missile icons of the appropriate size, so I guess you could just use those. Obviously this would not apply to Pit because his Hammers do not come in tanks.
