This add-on is incompatible with the "Maximize Message Pane" add-on. This older version does not have the ability to control which views are enabled. Compatibility notes: If you want to use this add-on with versions of Thunderbird prior to 49, you will need to download version 1.14. For the preview pane, put this in your 'prefs.

by modifying your prefs.js and userChrome.css files as described below. Finally, in the add-on preferences, you can select which views are accessible in the pop-up menu at the top of the folder list, and of those, which show up when you rotate through the views using the arrow buttons. You can change the background colors in Thunderbird's (or Mozilla Suite's) preview pane, folders pane, and thread pane (message-list pane), etc. In the add-on preferences, you can set the delay before the view is switched. This add-on adds arrow buttons at the top of the folder pane which rotate back and forth through the various available folder views This add-on also causes Thunderbird to automatically switch to the "All Folders" view when you hover over the title above the folder tree for several seconds during a message drag & drop operation, and switch back automatically after the drop. Current outstanding issues for Thunderbird 78 with workarounds are documented on Github.
