Allow interoperability with Django Debug Toolbar

It would be cool if the panels from DDT and Devserver were the same, and they only rendered a different template on output.

This would allow for an ecosystem of these style of plugins, I think. Totally a pony, but something worth thinking about.

I agree on that too.

Going to talk to Rob to see what we can do about this. I think it's definitely worth a shot.

So, any changes since then? :)
