We monitor 21 email addresses. For a long time, the Folder Pane sorted these addresses as we wanted, displaying the email address, and under that email address, the inbox, drafts, and archives. We may have accidently clicked on something in Thunderbird that caused the listing in the Folder Pane to change. The current display lists an email address, then ALL of the folders associated with that email address, the next email address and all of the folders under that email address, etc. This means we have to continually scroll down the Folder Pane to check which email addresses have something in their inbox. The way it listed before, and email address was displayed with its 'Inbox' and 'Drafts' folder, then the next email address with its 'Inbox' and 'Drafts' folder, etc. After that, a folder named 'Trash' was shown, and all the email addresses listed, a folder named 'Sent' was shown with all the email addresses listed, 'Archives', etc. After those, each email address was again shown with all of the non-standard folders under it, the next email address with its non-standard emails, etc. How to we return to the three part display as it was before? Did Thunderbird change or did we do something wrong? Thanks
