I think he means that when viewing all plugins, the activated ones should be lumped together like they used to be. I strongly second that - and is it just me, or are activated plugins no longer distinguished by having a green background? That's an odd "improvement", IMO.
And please do provide a way to disable the code editor - it's noticeably delaying the loading of my plugin and theme editor pages. It's a nice idea, like many of your radical changes are, but, like many of your radical changes, it would be better if you made it optional. There doesn't seem to be a whole lot of recognition of the fact that some people would like to be using principally the same piece of software for more than a few months at a time. It would be great if there was a way to get some of the improvements that come from the upgrades, without having to deal with radical interface changes every time we go up a .1 version. I thought the old plugin page was fine. So much for that I guess though.
Don't get me wrong, I'm a mad WP lover, but my upgrade to 2.8 is making things suddenly considerably more awkward. Not what I hope for in an upgrade - but that's beginning to become a companion "feature" to each serious WP upgrade. (i.e., having to re-adapt to major--sometimes questionable--"improvements" in the interface)
Anyway, there are probably some good, non-unsettling features in this upgrade too; I assume I'll bump into them eventually. Thanks for those! And thanks in advance for considering ways to allow us to have a stable interface for more than three months at a stretc while still following your recommended upgrade schedule. Because for now I'm going to start advising my WP-site having folks to just stay at one version (probably 2.71) for as long as they can stand it, to avoid jolting changes.
