I tried on linux (ubuntu) and it works fine so you can change that in the install instructions. Also some controls for moving on the X Y and Z axes would be cool cuz like it's technically possible if you rotate yourself around in 4d but it's needlessly difficult. I propose A/D for left/right, Q/E for ana/kata and W/S for up and down (forward/backward is already taken by the scrollwheel i think, worst case you can W/S for forward/backward and Z/X for up/down
Edit: i somehow missed the shift+lmb=pan thing, i take back everything i said about the movement lol. Although you could make shift+rmb=pan in the Z and W directions
