Awesome that looks great, seems easy enough.
On the Permissions I noticed that you could check or uncheck the permissions you want. I think that after making 20 links, that having to check or uncheck the same things over and over again would be tedious.

What if you had your checklist And a dropdown list Called "Permissions same as:" You could click the dropdown arrow and select a previous link item, it would then automatically adjust, (auto uncheck or check) your permissions to the see more same permissions or those your previously set up.
