How to place preview pane on left
I know how to place the preview pane on right with the vertical layout, but I would like to switch the place of the preview pane with one of the message tray pane. In other words, I want set the panes in a orders like the folder pane, the preview pane, and the message tray pane from left to right. I do not know how to do it so I would happy if anyone teach me how.

If you are willing to use userChrome.css, put the following CSS in userChrome.css. The following CSS should work for Thunderbird 128.9.0esr on Windows:
/* Vertical layout: three columns. */
body.layout-vertical {
grid-template: "folders folderPaneSplitter message messagePaneSplitter threads" auto
/ minmax(auto, var(--folderPaneSplitter-width)) min-content minmax(auto, var(--messagePaneSplitter-width)) min-content minmax(auto, 1fr) !important;
}
Please see the attached image, which shows the user interface after applying the above CSS.

There is no standard interface or command which will do this.

Thank you very much. I did not know about userChrome.css but it just works when I tried your CSS. I found that when I drug the border of the panes to change their width, it moves to opposite direction from my cursor drugs(CSS only define look of the interfaces so it is no wonder), though it is hardly a problem. Just for little notice. Again, thanks a lot for your helping.
