I like it too and accidentally posted the same thing elsewhere.
Jon Plummer: Have merged it! Along with your vote.
Anton Sklyar you mean when you copy Rich Text? Like bold rich text from say an Email or a website is copied, it should paste the markdown version?
Eduard Metzger: Exactly! That would be very handy. It could be implemented in different ways: for example, Bear app just does that conversion automatically when you paste text from a website or email, whereas in Ulysses you have an option "Paste from" and can choose to paste from rich text or html.
Anton Sklyar: Ok, got it. Have updated the title to clarify. I like this suggestion.
Thanks for merging Eduard Metzger, I didn't see the duplicate.
