Done except..

- topics

  should be trivial, copy from other and remove any stateful code.
  maybe addition: allow directory change notifications for reaload of

- navigation (prev / next)

  it's simple to add this to the index generation, but i'd like to
  also create nav for combinations of different sources.  maybe it's
  still best to put it in the index then.
