Oh man, I've been a fan of your app for so long! Have you ever considered an official iOS app? I think it's the only thing that keeps me from leaving Apple Notes.

I think the most popular app that derives from that code is TaskMator:

I might make another iOS app for TaskPaper at some point. But as an individual developer splitting myself across multiple projects and multiple platforms becomes painful pretty quickly.
