I just installed this add-on and it does exactly what I wanted. Thank you.

I have two questions. Firstly, what does the menu entry with the very long name actually do? The only difference I can see is that the next time (ond only that one time) I select "Remove Duplicates ..." I see a pop-up saying "not checking special folders".

And secondly, why are so many comparison options needed? Isn't it sufficient to just compare on comparing the message-id and date headers? (That is what my other mail client does, and I have always found it sufficient.)
