The gui for mobile is hard to navigate. Especially the action menu with flick styled buttons. Because mobile doesn't have vr features, the gestures are harder to deal with. We just walk around stiffly which is ok, but maybe add an easier way to access gestures than opening multiple menus. By the time we get to the gesture the person is gone and on a different topic.
Because we are stiff beings we can't draw in 3d space as well as someone with vr.
So if we can maybe get a better system for drawing. I have a recomendation for that in the images bellow. It's still clunky so if you guys have a better idea for that please do it.
I'm not familiar with coding so perhaps the ideas I have won't work but you get my general concept.
