Not sure if there might be a better way to implement this or not, but I've noticed that some interactions (including some of my own) use invisible characters to provide custom camera viewpoints.
Now this is fine, but I wonder if it might be better if there were a special "floating camera" character type; this would simply be a placeholder for a POV camera, only visible when editing. It wouldn't have any options like other characters do, and clicking on its name would simply switch you to its POV.
To compliment this, one thing I'd also like to see would be the ability to rename characters; this way instead of a bunch of "Floating Camera" entries we could have "Closeup", "Front" etc., as well as rename characters of the same species/type to clarify who they are.
