Yeah I agree on all fronts as well. I noticed it's now possible to rearrange studios (not sure when that was done), and already that's been a major QOL improvement. You'd expect all those list-boxes to work the same, so it's kind of strange that cameras and environments aren't there yet.
I recently finished a project where I had to visualize 6 concepts, with about 6 camera angles each, all with customized environments. You need to have a solid naming system in place and be very consistent, but even then an extra concept or a request for extra angles can make a properly organized project a mess.
