Rated 4 out of 5 stars

Although it accomplishes what it says, I don't think it's usually a good idea to have attachments automatically included in emails that are replied to. If you could respond with or without an attachment, that would be a five-star extension. When there are numerous attachments and you have to manually remove each one, it becomes quite annoying.

If "Reply with attachment" could be the third reply button, that would be a 10-star extension.
The first button is set to REPLY by default, followed by REPLY ALL and, if achievable, make 3rd one REPLY WITH ATT.

Very useful and easy to use. Hassle-free. Thank you!
