Rated 5 out of 5 stars

Identity Chooser is an absolute "Life Saver" for me! I own my own domain, and I have lots and lots of different email addresses using that domain. This helps me keep that all sorted.

Suggestions:
1. auto-sort alphabetically (by email address or by name?)
2. Apply the sort order to Thunderbird's Identity Manager.

AND

3. Add the ability to search for an email address in the chooser!
