Rated 5 out of 5 stars
Valuable add-on keeps one from sending those embarrassing e-mails from the wrong account, when replying, forwarding, or creating a new message! Forces user to choose the sender from a list of all defined accounts, whenever any of the above actions are invoked either by mouse or by keyboard shortcut. Options allow user to select which actions and which accounts will prompt for a sender.
Developer is very responsive to support requests. This user had problems which the developer spent time and worked hard to identify--and the problem turned out to be a conflict with another extension due to circumstances that most other users will never see.
Developer also willing to add a feature requested by this user to make available the same capability when "Edit as New" is invoked. When that is complete, my rating will be five stars.
Edit for version 1.6.5 beta on 2012-07-21: As promised, I am increasing my rating to five stars, now that the developer has added the ability to have IC triggered by the Edit As New command! This has been the missing feature/weak-link for me!
