Maybe a useful extension, but no information on how to use it available ... Rated 1 out of 5 stars

Could be a useful extension if the regex filter syntax would be known. Doesn't have any information, examples or else available to learn how to use it.
The home site isn't available for now.

This review is for a previous version of the add-on (1.2.0). 

Huh?

The home site IS available, with documentation, as can be found from links here or a simple Google search. I have no idea what is going on with this reviewer.
