The new layout for the plugins interface is attractive, functional and very welcome.The addition of a recognizable icon is also a welcome addition--any visual cue beyond having to read plain text is more than a cosmetic improvement. I've been doing the "bleeding edge nightlies" thing for several months now on a test site and I recommend it to anyone who has a test site they can spare for a few days or, better yet, a local testing environment. It certainly smooths the transition. Thanks to the 4.0 development team and beta-testers for all their hard work!
