Looks good so far! Using my Macbook I can't find a way to rotate or pan the camera without a mouse. If it doesn't exist yet, I suggest Unity controls which are:
Option key + drag to rotate
Option + Command keys + drag to pan
Also, Asset Forge makes my fan spin up in a few seconds and stay spinning as long as the program is in the foreground. Unity generally doesn't do that unless I'm actually running a game - editor usage doesn't use much CPU. CPU usage for Asset Forge is 60-65%, for Unity it's around 12%. It would be nice for those of us on laptops at coffee shops to keep power usage down. :)
