'Progress' is my middle name

[The Hobo]

I saw a wicked cool ProgressBar in some application not too long ago. I can't remember which program it was. But this morning I set out to duplicate what they made, and the attachment is what I came up with.

What I guess I'm asking is: what else should I add to this? What features should a ProgressBar have? What else should I make it do?

Thanks.
