I wonder if it would make sense to have an option where you could lock out a parameter from being keyframed regardless of whether Autokey was on or not. And there could be some glaring UI that indicates this (red dot on the node, or a red outline on the parameter or something)…
When we did a reverse user group a few months ago I proposed making Autokey a localized function so that you could leave it on on some nodes and off on others and it would remember that as you navigated through your setup.
Oh, yeah, I do the same. I was thinking you could keyframe the mux node.
You could, but that would put the same timing into every action in the batch with MB.
