"draft" feature

Sometimes it is awesome to work on widgets "in-line" and then "extract" them once everything is hooked up and verified as working.

It would be great if a particular part of the widget tree could be isolated out (virtually) so that you could focus solely on the inputs and the result for that one widget without having to dig through a lot of code. Once it's all working, you could then leave it where it is or the refactor tool cool extract it for you.
