I have three email accounts. I had the inboxes grouped under the inbox folder type (each account was listed with a folder labeled as Inbox (account 1) Inbox (account 2) and Inbox (account 3). The same for trash, outbound, deleted etc.. I just recently clicked on the drop down to see unread folders. When I went back to see all folders things had changed. Now the folders are listed under the individual account labels. I tried to find how to group by the folder types then the accounts instead of grouping by accounts and then by folder types. I do not remember how it did it in the first place either. Is there a way to go back? I am on Windows 7 and Thunderbird version 81.0b2 (32-bit). By the way is there a beta 64-bit?
