Suggestion: Advanced Camera Settings -> Target Object -> Select Axis
It would be really really nice if in the advanced options for a camera when you select "Target Object", that you can have the option to follow the target along a single axis. Sure this can be done using an OPE and a bunch of toolcards, but it would both save complexity and make such functionality more "axis-able" - yes I did just make a bad joke :D
My motivation for the above: I am running tight on complexity and am setting up a crash camera to point towards the rider by rotating around the Y axis and I thought it would be just lovely to be able do this using a simple checkbox.
