Hope you'll consider adding custom fields to pages in the future. This would solve a lot of problems for us devs wrestling to fit stuff into the backend so that our clients can edit things without our help. Being able to add meta tags and values that could be referenced as liquid variables would be a dream come true on the CMS side NationBuilder, and go a long way toward helping dissuade clients from opting for WordPress .
Thanks all! Let's consolidate notes on this issue here - http://nationbuilder.com/amplifychoice/add_custom_field_support_to_pages_and_posts
