@fede777 — re: CSS. You can do this on your own right now… for example, you can put <span class="related"> and </span> before and after the related entries, and then write some CSS for .related and drop it in your theme. Link formatting can be done with .related a as well.
As for the date and comments in the excerpt, I’ll put it on my 2.0 to-do list. Thanks for the idea!
