The theme I'm using has built-in custom fields that don't show up when editing with the free version. With the free version, i only see post title and post content. Will the built-in custom theme fields show up on the edit page with the pro version? I don't want to add new custom fields, I want people to be able to edit existing custom fields that have already been filled with data — also, if that is a possibility, will the previously filled in data show up on the edit page? (e.g. custom filed ‘price' will show previously entered price) or will it just be a blank form field?
