Sounds like a great widget. I have been asking for the equivalent of the windows quick launch bar since I got my N900 and this is exactly what I need. I note from the screen shot that it is not right at the bottom of the screen so there is a bit of space wasted. Can it be moved any lower or is that a limitation in the N900?

Also I presume there is an option to set how many items you want to put in the dock bar. Correct?
