HTML type for custom fields

It would be great to have a new type of custom fields which would render entered text as HTML.

This would let me do a whole lot of stuff, here's some examples:

• Display various badges on user cards, depending on their roles on my own website.
• Display icons of products they've bought.
• Display back links to user profiles on my own website.

I would fill these fields via API, so the basic text editing fields in admin area of UserEcho would work just fine for me.
