I once had a very frustrating battle with a new reviewer who told me my utilitarian app did not offer an "innovative experience" and wasn't "interactive" enough.

So I had to add a completely useless feature where a user could partition their database by marking some items as "favorites" and have a separate "favorite" view.

This was then approved, with the assertion that "it's now the magical kind of experience users expect from the App Store."

I'm pretty invested in an Apple ecosystem for some very specific software, but that was nearly enough to make me ragequit (unfortunately, the specific software is not something I could develop/imitate under Linux without a huge financial investment).
