htmlpopup-content

yep, good point I'll change that.

How hard would it be to return simple key/value pairs instead of the html?

It would be tough... Just look at the diversity of templates we have at the moment. It is a huge mess. Out of scope at the moment. I don't think we have time for that.

Regarding the styling issues (tooltip and result panel), a quick way to solve that would be to pass an extra parameter and adapt the css class in the mako template accordingly.
