I have only ever had one email address on Thunderbird for the last 17 years or so and now I have added some more email addresses. Each email address is listed on the left, however, in other email platforms there is a generalised view with inbox, sent., deleted etc., on top of the separate email addresses so that you can see what's come in or gone out without going to each address and dropping down the menu on each one to see if you have emails. Is there a way to arrange this so that one has a general view of all one's email activities on top of the individual addresses just as they have in Outlook or Apple Mail please?
