I have conflicting thoughts on this one. I can see how to the average user would find this extremely handy. I, myself, get frustrated digging through style so I can add a single link or two. But, I would also hate to have a link attached to that module in the same way that tags does.

A lot of users, myself included, heavily customize the link list location on their layouts to better integrate it with the theme, or make it easier to access. They'd have to remove that link via css to make their layouts work the same. It would be handy if the user displayed the link list in a common column layout, but to a user who heavily customizes their page it could be an issue.

Perhaps an option for it (a check box), but not a requirement?

Ideally, I wish links like the ability to manage tags or link lists (where applicable) could be in the navigation strip.
