the media preview is a nice feature. But it has to have independet rendering setting than the main live view. The image might have been set up as path tracing but you want to make changes in a standard realtime view.
This could be made possible by being able to leave media mode without having the preview disapearing.
thank you for you message. I will submit that. Since I have more suggestions: should I submit each idea separately or can I just make a list with descriptions?
Don´t know how these ideas are managed.
