Bungie could be fully utilising the PS4 controller
We all know what a hassle it is to pop a synth in the heat of battle!
How about Bungie gives PS4 users some extra functionality on the controller touchpad.
When you click on the touchpad to bring up your options to go to orbit or summon your sparrow it could also display a semi transparent view of just your consumables.
You could then use the touchpad to quickly run your finger over to select the appropriate consumable & bingo! Synth popped etc!
2 clicks which would mean you could pop a synth in a split second in the heat of battle & you'd still be situationally aware with it being semi transparent.
This would surely be fairly easy to implement. How about it Bungie?
