The opinion I was trying to convey in my first post is that Corona UI is somewhat unrefined in some places. Can't understand those blue arrows and bad placing at the right on the image I sent above. Seems that Tone Mapping Settings Editor accessed via "Edit" on camera controls is a copy-paste of what we have in Corona VFB without removing the arrow left of Tone Mapping, which doesn't serve any purpose. I know it's a little thing but to me, it kills the usability and pleasure of working with the software.
