link-manager.php needs an Attached to column

Look at the ‘Media Library’ section.
The ‘Attached to’ column is useful. Allows one to associate media to a post.
This is great, I can then code something to show the attachments, that’s how I do this.

It is very- *very* common- that a user or wordpress wants to add a link in their post- and it’s hard for them to do so. I’ve experienced this with various clients.
I installed a hack to turn apparent urls to a tags, and thus show a link.
Great.

But the real solution is something like allowing to attach links to posts. Just as you do for media.

Before I go off and start hacking away- Is there something like this in the plugins section? I can’t find it at all.

Please forgive me if I am posting this to the wrong place. This is my first post, please feel free to reprimand.
