I am a hobbyist computer graphics programmer using the Ogre3D API I have done better camera action then FD debug camera which is awkward to use like my way would of been rotating all around the viewing objects using a mouse x and y and zooming in and out a good distance would of been very nice that way for FD to setup. That said would of like to zoom out a little further and got some quick selfies of some quick combat videos of my turrets firing at a target at a distance.
FD need to cater for every type of control, from keyboard to gamepad, so they can't rely on anyone having a mouse, whilst I agree completely that it would be so, so nice for that to work properly! Also, they are highly, highly unlikely to change it much over time. There's a very minor exploit just now to do with docking, where the debug cam gives an advantage over not using it, which I believe breaks its current design brief, so we might even see "5 seconds of dead controls after leaving Debug Cam" implemented to cancel this out. Weapon firing would be lovely, but it ain't gonna happen in this galaxy.
