I was also thinking of doing 2-3 widgets - mainly to create a MCP widget procedurally by iterating over the ND hash and creating a button/checkbox for each option.
This should also help for the MapStructure "widget", because we're adding widgets there to easily toggle layers on/off, so that we don't have to use PUI:
So, I'll help with the tutorial, and I think Necolatis also said a few days ago that he was going to help improve the wiki article (which is currently just a stub). So I am sure it will grow quickly - ultimately, we may ask Tom have another look and establish some "best practices" though
However, if in doubt, please update the wiki accordingly, and add your nicknames there so that people know what widgets are being worked on, and by whom:
