Dear Thunderbird aficionados, I would like to change the appearance of the the main Thunderbird page, i.e. the one with the list of messages and the column of the mail account folders. In fact, I would like to have it with larger fonts and with a larger spacing between lines. I tried with Theme font and Size changer, but I cannot manage to have a view which is not very packed for my eyes and I would like to know how to change the font size, the font itself and the spacing between lines, at least. How can I do that? Best regards, pietro govoni
