Rated 4 out of 5 stars

Nice classic look for TB 3.1
Good if you want to everything set up like older versions.

If you like to use buttons on the message header, you may not like this. The button icons there do not look too good.

The problem stated by FeatheredGems does not happen on WinXP sp3 TB3.1.

This review is for a previous version of the add-on (1.3.1).
