Hello,
Here are some keybinding suggestions that I would find useful:
1. Tilt Camera Up/Down. This would be perfect for use with the analog stick of my Razer Tartarus Pro, which I use to look left and right.
2. Target Interactable NPC (vendors, mission givers, etc.) and Objects. To follow the current trend, it would probably be (1) Target Nearest NPC/Object, (2) Target Next NPC/Object, and (3) Target Previous NPC/Object.
3. Interact. Basically acts like the right click used.
Thanks for your consideration!
