CloseReview for Contacts Sidebar by WebWeaver64
Rated 5 out of 5 stars
Love this addon, however it isn't working in 3.1 and the suggestion by iminj does give a sidebar in the Write window, but now in the main view area. I'm ::::crossing fingers:::: that an update is on it's way. Searching across address books is a total PITA without this addon!
