Whoa, I did it! My currently playing iTunes track shows up in the “dock” and you can also view a list of my 10 last played tracks. Some tweaking and such will be done in the hours and days ahead (and the auto-update feature is not working yet!! Argh!), but at least its there.

Although perhaps of little use, I made a little discovery today: double-clicking an image inserted in a text document in TextEdit, will open the graphic in Preview.
Update: Restarting Kung-Tunes a couple times seemed to fix the auto-updating. You should now see updated stats whenever I’m playing something (and another lil message when I’m not).
