Rename: Allow direct editing of current filename

 "Custom Name" or "Edit": Please populate with current name. Allow direct editing. e.g. current name “Alaska_1034.nef”  “Show Alaska_1034.nef” and let me delete “Alaska_” or change it to “Yukon_”

And: include button <Copy File to New Name [same folder]> which leaves old file with old name untouched
