Yes, Yes. A thousand times, yes. I love being able to switch to different combat styles, but it is always such a pain to have to go into various pop-up boxes, just to switch what I've already programmed. It would be so helpful to be able to create a draggable icon that can be placed on the quick bar, so players can quickly switch between loadouts that they've already created.

Push-to-talk is not necessarily required. It is recommended, but not required, while in-game.
