Software Camera Hotkeys

I would love some options to change how the camera hotkeys work, maybe you can switch between default and 3ds max camera hotkeys for example.

Not sure about hot keys, but they free form style of camera orientation seems odd compared to animation software, where there is a definite and constant ‘up’ to the camera.

Especially when you are trying to keep parts aligned to the horizon/ground plane, it’s tough to tell exactly what is straight up while in a perspective view because the ground plane is twisting around as you examine the object from different angles. This is important for exact part orientation, when the part needs to be just right in order to print.

Is there a reason for this style of camera control?
