* Future
  - Syntax highlight checkboxes and checkbox cookies
  - Separate syntax group for heading delimiters
  - Syntax highlight and indent "properties"

* Maybe
  - Implement Emacs's abbreviations (e.g. '\<s<TAB>')

* Impossible?
  - Try to get text attributes to stack (e.g. underlined text in bold text)
  - Close inline block using same number of starting delimiters.
  - Set a max number of lines to search for end delimiter for bold/italic/etc. to 3 (might not be possible)
