What I’d really love to see is a “clone” of the Ellis Labs network running where we could access the admin CP and then see things reflected in a “live” site. (Surely, the best examples of best-practices and efficient use of features would come from the makers of the product!)
Many CMS sites have demos of their products that get “reset” every day or so…. That way, people can log in, see how things are implemented by the creators, play around a little, and then everything gets reset at the end of the day…
I’ve found the blog posts about various feature implementations on the EE site very, very useful. What a huge benefit it would be to us if we could see the whole big picture at once!
