A few new features were implemented in the latest WordPress 2.3. One of the additions was integrated tagging support. If you were using other tagging plugins previously, you can import your tags using the importer tool. This is a great addition to the core system but it lacked visual display for the available tags. There should have been a section that displayed all previous used tags just like what is available for the categories section.
Click Tags was developed to overcome this problem. It adds the list of tags above the textbox so that you can easily select a previous tag to use. This helps to keep your tagging consistent.
I still haven’t upgraded to version 2.3. I have read some people having problems with it. I will consider upgrading when I have the time next week.
