Very cool plugin. Thanks Steven.
One thing I've noticed. I usually have 5 tabs open; Music, Playing Track, Visualizer, Now Playing, and Inbox. If I click on the new tab "Last.fm Stats" in Now Playing, works great. When I switch to the Playing Track tab, where the new "Last.fm Stats" tab is also visible, when I click on the "Last.fm Stats" tab, the panel remains blank.
Is this something in my setup?
Anyway, small thing as this new plugin rocks!
