Duplicate titles in multiple tag pages

Hi Doron,
1.In Joomla I have 180 tags pages and 98% has the same title which is taken from a blog article. That considered a duplicate title which is an SEO issue. How this plugin handles that.
We are module and will show module based on selection.it is kind of similar to tag module available in joomla.
2.Does this plugin warrens you of duplicate tags in the same blog article? As far as I understand a unique tag should be attached to the blog's article.
We show tag available in tag.so there is no chance showing duplicate tag in module.
3.I have many blog articles with multiple tags that are shared in different articles. I need to do some clean up. Does your plugin help in this process?
No

Regarding item 3 that maybe something that you can add.

Thanks,

Doron
