It’s supposed to morph the site theme into something more basic, for those that like it clean, simple and with less interaction options. It’s not coded yet but it’s a feature request we get from time to time and will be part of an upcoming content type (not site-wide).
I would be pretty satisfied withe a simple “star” icon that would toggle the document (wiki and others) being on my favorite list or not. Then on “my profile” page I would like to see a list of my “bookmarked” documents.
I’m glad to see that you guys always have some great ideas, and the team is really trying to make these real. Thanks for that! :) I think we will soon have a great site, with many articles from a great developer community! :):):)
