Poor / not complete Rated 1 out of 5 stars

Its a great tool, but it didn't work with over 50.000 messages (that could be explained by our very slow responding imapserver)

1 major drawback is that this tool needs to make a copy to the trashcan which slows it down considerably.

This review is for a previous version of the add-on (0.3.3).

As for the first issue, this is not true - you can choose to erase completely rather than move to trash.
