Plan for 2.x

Gathering ideas for a possible 2.x version.

Tokens
Consider supporting tokens in headline, sub and super fields. This could replace the current "Use entity title" functionality (it's unexpected to me that the headline doesn't update when entity title is changed), and super/sub-heads could be based on other fields as desired.

New formatter/markup pattern
The previously recommended markup pattern, e.g.:

<h2>
  <span class="super">Super headline</span>
  <span class="headline">Headline</span>
  <span class="sub">Sub headline</span>
</h2>

has been superseded by a newer pattern based on the hgroup element. Ideally, this would become the default formatter.
