Seconding (or would it be fifthing by this point?) default WASDQE camera setup, most FPS's use these keys for camera/character position control for a reason. As for hotkeys, using ZXC-RFV works, since they are right next to WASD. Not to mention Shift and Ctrl combos. which can be done easily under this schema. Also, instead of using just one camera mode, why not use the 3 most useful camera modes, using TAB to toggle between them?
I want to make one point to the camera. The pole-lock is great, but would it be possible to "scroll over the pole-point"? Now the camera cant go over it. so you have to turn it first and then you can scroll again... I would love to see this working.
Maybe making the pole-lock-axis "flexible" by a few degrees when moving the camera close to one of the poles might help.
I bring this up once more, since there arent any new post here for a month. What do you guys think of my idea:
Totally agree with the WASDQE set up for camera movement, or the chance to set our own keys would be good too.
