I believe most if not all players would appreciate hotkeys. From what I've read most people just want ammo synthesis hotkeys, but I've come up with an idea for both ammo synthesis and glimmer increasing consumable hotkeys. You should have it where clicking R3 brings up a D-Pad in the bottom left corner of the screen that shows each of the ammo synthesis, one on each arm of the D-Pad (Excluding the bottom one of course). This should also show how many of each you have by the little pictures, and how much time you have left before you can use another in the middle of the D-Pad. Now, for the glimmer increasing consumables, double clicking R3 would bring up the D-Pad for these. One on each arm and how many of each once again. And when you are trying to select one that you have taken within the last 10 minutes will result in the time remaining showing up in the middle of the D-Pad for 3-4 seconds. Or if you think it would be troublesome on the bottom left, flash the time for both ammo synthesis and glimmer increasing consumables closer to the middle of the screen. Also, I just thought about it, you could have the placement customizable. Meaning the player could put the item on whichever arm of the D-Pad that he/she wanted. Once again, I believe most if not all players (Including myself) would like to see this in the game on the next update.
