	Things that may/do fail, and things I'd like to see added:

- Use arrow keys to change pages, maybe zoom (James Reeves).

- Add a 'memory' of the last page viewed, so it's easier to
  go back there. Maybe add a 'go to page' command too?

- Memorize the window size on exit too.

- Add an archive generator

- Prefetch next page(s) (Seth Cohn)

- Fit to screen (Seth Cohn)

- Rotate pages (Seth Cohn) - This is quite slow or resource intensive,
  will look into it

- Dual page (Seth Cohn) - Was in the works, but I'll put here to increase
  the pressure on the author (me).
