So I made a start – imported some stencils into OmniGraffle on the iPad and just had a stab at it. I think this is going to be better – previously I’ve tried to work out stuff like navigation layout while designing and I always end up in a muddle – this was better, to be thinking about what should go on the page without worrying too much about what it would look like, where it would go and the prominence it should have in relation to the other content. A well-worthwhile exercise.
