From where I can add a link at the bottom of Tag cloud?

Hi Rickard Andersson

Thanks for this Awsome plugin!
just need a little help. I want to add a link to show all categories of the respective taxonomy of which I’m displaying the cloud just like in this link

Done with the page with all terms of that taxonomy. Just can’t figure out where to add the link in your plugin’s php files.

Just to let you know that I am very comfortable in customizing the plugin code.

Any help in this regard will be appreciated!
