Well, we are in a discussion forum, so I felt fine asking a personal question about your choice, and opinion of such. If you don’t want to directly answer the question, that is your prerogative.
From what I can infer, you are looking for a rich text editor with outlining functionality. Along the way, you have (justifiably, IMHO) taken a liking to TaskPaper’s features, including tags, focus and folding.
The inherent danger of this is that TaskPaper may never fully meet your needs/desires. You are trying to shoehorn a to-do list manager into a writing environment.
Things are further complicated by TaskPaper’s support of stylesheets and scripting, which are tools that may solve some of your needs/desires, if you roll your sleeves up and dig into them.
So, if you decide to stay with TaskPaper, you have to either: put up with a shoehorned tool; wait for Jesse to add features in a future version (which may or may not happen); or try to create suitable scripts and a stylesheet that helps to improve the display of your text.
I would suggest trying a tool better suited to styled writing (as opposed to plain text task management). For this, I’d heartily recommend Scrivener or Ulysses. Unless you have fallen in love with TaskPaper, I’d bet that you would be happier writing in one of these two apps.
Just my 2¢.
