Best there is, but needs more. Rated 4 out of 5 stars

Seriously needs the ability to search under more/custom header lines. If you operate from a saved search folder instead of an account folder, the utility of Nostalgy is extremely hampered.

Also, tried posting to the email list, but no response, and zero traffic on the list.

This review is for a previous version of the add-on (0.2.20).
