Rated 4 out of 5 stars

Before TB 115, I could hit CTRL-M while I my target email account was highlighted and it bypassed Identity Chooser, which was great. No extra step. Now with 115, I cannot bypass. Wish you could bring this back. Thanks.

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

Not reacting to Ctrl+M was a bug and not the intended behavior. Identity Chooser is all about forcing the user to explicitly choose the sender identity. In TB115, Identity Chooser works as intended.
