Doesn't work.

At this point it doesn't seem that this module does much. It shows a "Click to bookmark" link when you view a node, but the links it generates all go to the front page. A couple of suggestions:

• Show the "Click to bookmark" link with every node. So also in the teaser.
• When a node is already bookmarked show a "Remove bookmark" link in stead of allowing to bookmark one link several times.
• This is an excellent place for applying jQuery. Bookmark the node without reloading the page.
• The admin screen let's you choose between different node types, I don't think that's necessary. If you don't have that option your code also becomes easier.
