The way the auto key recording button fires up presently is pretty weird and confusing. And if it's recording keys then dangerous too. What would be useful and hasn't existed since 1x is being able to scrub a global timeline. For eg I have a keyframed character moving and a camera keyframed but I cant scrub both at the same time. The result being I cant scrub forward and line up my camera with my character because both can't be scrubbed forward at the same time. I have to guess where the character might be, and line up the camera looking at a space where he isnt, making for sloppy design. Thats been a long time gripe for Unity animation editing for me.
