Feature or improvement you want

It would be nice to have changes saved from the Edit Feed screen after pressing the back button from the navigation bar. Using a dialog box to prompt the user to confirm changes and saving it that way or saving by default after pressing the back button would be helpful.

Why should this be added?

I believe this would be a nice quality of life change. I find myself editing my feeds but forgetting to press the "ok" button at the bottom since it is not immediately visible without scrolling down and instead leaving the Edit Feed screen using back button from my phone's navigation bar which does not save my changes to the feed. Making this change would make it so users find that their changes are saved even if they forget to press that "ok" button.
