Use case or problem
I’ve noticed that the text editor doesn’t quite feel “right” to me. And this might be why: When you scroll to the top of bottom of a file, the scrolling just abruptly stops. In native (macOS, at least) apps there’s a nice “bounce”. This is sometimes called “rubber banding” or “elastic scrolling”.
Proposed solution
Add the bounce behavior. (gif recorded in iA Writer)
I know this request sounds ridiculous, but it’s one of those tiny details that would make the app get even more of that nice, premium, native feeling that makes me happy to spend time in it.
