nope, just have to figure out how the cameras are MEANT to be used.
I keep a 'render' cam permanently assigned to the renders, and use the other cameras as reference points only. When I want to pan somewhere else, I then switch to 'perspective' camera, which follows you wherever you go. Once I've lined up a shot, I snapshot it to the render cam. If I want to come back to that spot later, I'm forced to create a new camera just to mark the spot.
The hard part to learn was switching to the perspective cam. Otherwise, when I pan around, I'm turning whatever camera that I switched to, ruining it's reference point Having a lock for the cameras would be nice.
Even better would be a different system. I'd like just one camera and a flexible bookmarking sytem. (more cameras are ok, although I don't really see the advantage. A really good bookmarking system could also remember different camera settings like FOV and exposure.)
