I'll be the first to say it in these comments apparently, but I am absolutely thrilled by these improvements. Combine the improved install details with the new "card" design, http://screencloud.net/v/opKb, and the plugins section is really beginning to shine.

Considering that plugins are one of the primary pillars that allows WordPress to power such a significant part of the web, I'm a bit surprised so many people seem to be against these improvements. It only makes sense to make it easier for users to find plugins and understand what they do.
