Thank you for your review!
I am still working on this project, not sure how long it would take to be done. The requested addition is already implemented in version 5.0 of Multiple Camera Render, but there is a lot more stuff to do here (maybe I planned too much for that release🙂)
Works quite well for rendering multiple static shots from a single scene.
Only thing missing for me is the ability to sort cameras by name, besides the already provided Clockwise and Counterclockwise options.
