Rated 4 out of 5 stars

Just what I was looking for. When replying to or forwarding a message, it would be great if there were an option to just default to the email for the the identity the same as the "To" email address instead of being forced to choose.

This review is for a previous version of the add-on (4.1). 

Thank you for your comment.

You can deactivate Identity Chooser for replies and forwards in Identity Chooser's settings in the addon manager.
