I often find myself in the situation that I browse the SE sites using my mobile browser (since I find it easier to keep multiple sites and questions open the same time) and then want the edit or answer a question.
I think the editor of the iOS app is much better then the mobile website experience, to I had like to open the question in the app to do the things I want to.
So I propose to create an open in app
button on the mobile website, or another (easy) option to open a question in the app.
