Until the past few days, whenever I opened Thunderbird, the screen showed "Inbox-local folders" at the top of the left column, with all my local folders, including "sent', "junk", "trash' and all of the local foldrs I created listed in that left column. Now it says only "inbox" on the tab and shows only my inbox messages. I expect I reformatted it by mistake. What can/should I do to be able to see and switch easily between "inbox" and my oother local folders. Thanks for your help!
