Editor Navigation Controls Customisation

Hey guys,

Is there any reason certain elements of the navigational system in the Editor aren’t customizable?

For example - I’d really like to be able to change the Camera Tumble from ALT + RMB to MMB - and the Camera Panning from MMB to Shift+MMB - as well as binding Selection Focus from “F” to MB4

Giving this sort of customization would allow a huge fluency between 3D modelling software’s like Blender, 3DSM and Maya - Currently for myself and many others there is like a 30 minute adjustment period while our brains adjust to between navigation, which is a real headache when flipping between softwares to tweak geometry, uvs etc.

If there is a way to get around this it would be great.
