Navigation in sidebar

Hi,

Thanks for a great plug-in that does almost exactly what I need. I’d like to position the page content navigation in the wordpress sidebar, but it’s tricky to do this with CSS alone. Can you suggest a way to add it to a text widget? If that isn’t possible would you be prepared to look at modifying it for a fee?

Thanks
