It would be great if there was a quick way to swap weapons on the fly rather than going back to the character screen. It's a pain when you're in the middle of a gun battle and an enemy shows up with a solar shield and the only weapons I have equipped have void or arc damage or vice versa. One way it could be done is if when you click on the touchpad on PS4 (or equivalent on other systems) if the D Pad could then be enabled to switch primary, secondary or heavy weapons rather than the default dancing, pointing, waving or sitting. It would also give ghost a useful function (other than his slow hacking skills, summoning the sparrow or taking you back to orbit).
