Would be nice to have a kind of "my own default setup of columns" function. In a topfolder, say Inbox I have arranged the columns I'd like to be present all over all subfolders. But Thunderbird apparantly does not work that way. Making a new subfolder somwhere I have to copy the layout from one folder that I prefer as my own general default layout and use the right click function "Apply columns to ..." .... every time making a new folder. That's a bit tiresome. It ought to be possible to have a function "Update default column layout" to my own liking. If it's already there please advice as reading forums and searching online does not give me an answer to this. Cheers
