[Plugin: WP User Frontend] Question about using Custom Fields

I’m liking this plugin so far, but how can I set it to display existing custom fields? In other words, if I am already using a custom field with a name and value of ‘price’, how can I add that same custom field to the plugin?

Also, there’s no way to add additional custom field/taxonomy types, such as images, links, radio buttons, etc? I’m ok with using an additional plugin for those types of taxonomies as long as I can mirror those fields in frontend form.

Thanks.
