What is a MULT ? What is a JUMPER ? Thank you

I have a few suggestions about air-dropped supplies in the game, that may make game play easier & more fun. Suggestion #1 Currently, if you pick up a First Aid, Shield, N2O, or a Nuke, you have to use it immediately. If you pick up a crystal box, it goes in your bank. -Why not bank the supplies as well, and then each player can use the individual supply when they really need it? Sometimes a First Aid kit is in front of you when you have full health, and do not need it, Sometimes, when you REALLY need a + kit, you cant find one. Suggestion #2 Add Mines to the dropped supplies. That way, all 5 usable supply commodities are represented, not just 4 of the 5. Just my opinion.
