Its very useful in a compact format

I use style 16, 24 hour clock, and size it and move it just next to my dock. This style shows time, date, and day of the week in a colorful, easy to read display and shows time both in digital 24 hr and and analog 12 hour am/pm format. I start it automatically when I logon. It shows on all desktops (I have 7). However in Lion 7.4, it does not float on top It. Between boots, restarts, and logoff/login it does remember the style but not its last position on the screen.
