I am missing the Mouse Button 4 and 5

Hi, love the software it is awesome, and it makes my Star Citizen experience so much more immersive.

But, I would love to be able to use my Mouse Buttons as usable keys in GameGlass in my case the free look camera is bound on Mouse Button 5 so I can simultaneously Move around with my WASD keys and look around with Mouse Button 5

In the end, I think it will be very useful for everyone to be able to use their mouse buttons
