Hello,
Your addon is excellent, bravo.
However, since the update of 45 TB, shippers (or correspondents in French) are no longer in bold if their message is not read.
Would it be possible to restore this very practical function?
Thank you for your work.

Questa recensione riguarda una versione precedente (9.2) del componente aggiuntivo. 

Cannot reproduce this problem with Thunderbird 45.

When you say "shippers", do you mean:

- account names in the Folder Pane ? - or
- Inboxes in the Folder Pane ? - or
- senders in From column of Thread Pane (message list) ? - or
- titles in Subject column of Thread Pane (message list) ?
