Dunno if it's been mentioned, did a quick search and found nothing.
The free-view camera that you control with mouse.
If we where able to assign axis to this.
This way we could use our expensive HOTAS setups to actually make some nice tracking shot's inside DCS, the quality of DCS youtube material would increase.
Apologies in advance if this has already been mentioned. (or if I have yet to find the axis settings)
