Rated 5 out of 5 stars

Thank you! This is add-on is great. I have been wanting the ability to customize notifications by account (folder even better!) and to run an external command for years.

Suggestions:
I would love to see three changes to the notification window:

1) Currently only one action is allowed on the click of the notification window. I would love to be able to either close the notification or open the message. Would it be possible to allow a single-click and a double-click action or a right-click to pull up a context menu?

2) Would it be possible to show the first line or two of the email body in the notification window?

3) I would also second "osa"'s suggestion of seeing not just the last email alert, but the previous 10 (or so).

Once again, thank you for making this add-on and sharing it with us.

This review is for a previous version of the add-on (0.16.1).
