There are two sub-modules: one that lists all the keywords extracted by the tag cloud and one that allows to manually add new banned keywords.

With the first sub-module, you can click on a page and you'll see all the keywords that the “Better Tag Cloud” plugin will show in that page in the FE. For each keyword, you can see the number of occurrences and you can disable it.

In the second sub-module, you can add banned keywords before they will be listed in the previous sub-module. This is very useful if your keywords are extracted from contents inserted by FE-users. In this way, you can add keywords like “sex” or “shit” in the blacklist to prevent their presentation in the tag cloud.
