I just wanted to say Thank You for automating the plug-in upgrade process. It's so great that I can just click "upgrade automatically" and everything is taken care of.
I hope that the upgrade to future versions of WordPress also goes so smoothly and simply, as upgrading was a big pain in my butt. It's the reason I waited two extra months until 2.7 came out to upgrade.
There are lots of other usability upgrades that make 2.7 great as well, but the automatic upgrade is my favorite!
