Yes, I mean setting a specific y axis height. So that when you start SteamVR, the height is always set to that position. So that if the height changes during a game for some reason, it will return to the default height the next time I start SteamVR. Right now I have to run the Room Setup every time, or use the controller move function to get back to the correct height.
I think if there was a feature in Driver4VR to set a default position in the UI, it could be useful for many people without positional tracking, or people who only play seated with an xbox controller.
