When navigation laser scanned 3D spaces I feel like playing old computer games from when the best way to move around was not yet established and key bindings was not adjustable. All these different commands to navigate in different ways just feel too complicated and clunky, I feel it could be simplified by implementing some ideas from the modern fps gaming world.
Its simple, just implement the W-A-S-D + Mouse - Scheme
W = Move forward
S = Move Backward
A = Strafe Left
D = Strafe Right
Mouse = Look Around
Combine these with some simple hotkey for measuring and the ability to configure key bindings to your liking etc. And i think we´re golden.
