Would be great to be able to choose whether a layer could always stay on top or not.

For example a camera. Every time I add layers the camera slowly goes down in the stack and I have every time to drag it on the top cos I need to see its keyframing obviously.

Same for Audio File. I know I can put Markers but in some cases I need to see the waveform as I am doing very specific timed animation.

Same for Guide layers. Why they don't stay always on top as I need those to guide my other choices.

This idea come from Cubase. I also make music and in there you kind of have a double timeline and you can put your Audiotracks (equivalent of layers) in either timeline. One stays always at the top and other behave as you would expect.

Please check this Cubase tutorial that explains the two timeline panels. It's only two minutes
