In a future release, I'd like to see an extra-small setting. You can also alter the look of the palette and its icons by changing its 'skin'. In addition to the default QuickTime 4 skin, four optional skins are part of the A-Dock download. And, if they aren't enough, you can download other skin designs from A-Dock's skin page for free. See a couple of examples below.
Documentation is organized and clearly written.
Quick download of about 235kb and easy installation. After a couple of weeks, you'll get startup reminders if you haven't paid the shareware fee.
