Thunderbird at present automatically sets up all folders (new and old) with threading, sets up new folders with 'Correspondents' instead of 'From' and 'Recipient', and with messages arranged in ascending date order. I do not want threading, but every new update re-sets threading as default on all my folders.
I understand that there are technical fixes to get around these problems, but I want simple global menu options to set my preferences, preferably permanently. If permanently cannot be arranged, then a simple global menu setting which I can reset after each update of Thunderbird, instead of needing to go through all my many folders to 'unthread' them.
Setting global folder options to 'From' and 'Recipient' from 'Correspondents', and setting messages in descending date order would save me the hassle of re-setting every new folder when I create it.
