I received the following from thunderbird I have 115.2.3 https://blog.thunderbird.net/2023/08/make-thunderbird-yours-how-to-get-the-thunderbird-115-supernova-look/

  1. Turn On Cards View is not possible to view, Message List Header can not be found in vertical, classic or wide view
  2. Turn On “Tags” Folder Mode can not be found under ... in folders configuration

I have tried toggling multiple views on and off but the message list header option is never shown. How do I find this ?

Message List Header is under View/Layout. When it's visible, click the Quick Filter toggle button to show the filter buttons, for Tags, Unread etc. The Cards/Table icon is at the right end of the Header.

There is no, as I stated, message list header under view layout. I have attached my screen capture

In the attached pictures you can see the option in the Menu Bar or the AppMenu. Test for a broken layout by running in safe/troubleshoot mode (hold Shift when launching TB).
