Oh Dear Rated 1 out of 5 stars
Something's wrong with the latest update for me anyway.
I'm not impressed that the update caused all my account colours to disappear. even worse, it conflicts with 2 add-ons I'm using: "Show InOut 0.602" and "Address Book Display Name 0.2.2a (experimental)". Both modify the thread pane to show fields from the address book rather than the default 'To' 'From' fields. Both worked prior to the update. After the update, neither extension displays any entry for the sender's details, although the default fields work. No facility to go back to the previous version so this extension is disabled until it's fixed. I hope that's soon.
Conflicts & Migration
Release 3.1 fixes these problems. The conflicts with "Show InOut 0.602" and "Address Book Display Name 0.2.2a" have been resolved. The color settings are now automatically migrated from Release 2.0 and Release 3.0 (To do this: Install Release 3.1, open Options dialog, click OK to complete migration).
