I think it would be beneficial to add the "add this page to my watchlist" blue star widget to each item in Special:UserContributions. I often add pages to my watchlist out of my contributions; in my case I do it using the Popups widget, but I'm sure that most people don't have that enabled. I would suggest having it on the left-hand side of the list if so.
