Considering the list of requests and suggestions open and pending, I am not sure if I should add up one more to the list I hope you will accept one more idea.
Since we went away from film so fast, it is a bit outdated to have "Film type" field in the "Edit Image" form. Probably we would need a selectable option for "Film Camera" versus "Digital Camera." Film Camera could than be accompanied by "Film type" and "Scanner," digital Camera might be accompanied by "Raw Converter."
Just a thought, to add even more to the searchable database of attributes!
