In-game IPD Interface - Small Change Request

I personally would love to see the ability to change the in-game "IPD" values via slider and/or spin buttons (numeric updown).

Right now - while wearing a VR HMD, one has to hunt-and-peck for the correct numbers on the keyboard, which is rather frustrating.

While at it, could you change the naming convention to be 'World Scale', rather than 'IPD'?

(IPD is what the optometrist determines, and the player dials in on their headset as a value in millimeters; they are not the same thing)
