The new export menu requires more clicks.
I used to be able to tap on (I'm paraphrasing because I can't 100% remember the wording) "export to photos app" and it would remember my chosen file format for that export destination. And when I choose "export to files app" it remembered my chosen file format for that too.
As in, I could just choose one of those two to export in the file format I want. I work with TIFF when I edit in other apps, which is when I export to the files app. And I export jpeg to the photos app when I have my finished edit.
the new menu forces me to switch back and forth and is more cumbersome. I do not see it as being better or more convenient.
I hope you can bring back the old menu.
