firstly, i'd like to say this isn't really about settings, well it sort of is, it's about layouts, but there's no heading for that. sorry! i've just gone from version 102 to version 128. for my use of Thunderbird, nothing much seems to have changed, except some things are now harder. (such is progress!) i would like to see the columns in message lists as proper columns, with headers you can click on. so only one line per message, as it used to be, would suit me just fine. that way i can compare things in the list, which i would say is really important. you can change the sort, and easily see how it effects things. does anyone know if is there any way to achieve this? i can't see anything in Settings or View. thanks so much.
