The current functionality of turning a field into a link or image is great, but I've got a few use cases where it needs to be more flexible. For example, I'd like to have an image that's hyperlinked, or two links from a single field, or even just render a trusted field which contains HTML. How about a Raw type, where you can enter a fragment of HTML that will be used eg.

<a href="http://server/doSomething?{{value}}"><img src="http://server/images/{{value}}"></a>

or

Lookup in <a href="http://server/system1?{{value}}">system1</a>, 
<a href="http://server/system2?{{value}}">system2</a>

or

<b>Field contains: </b>{{value}}
