Perfect! This add-on provides a toolbar button which lets you toggle between classic, wide, and vertical views. Normally I use vertical view, but when using ThunderBrowse classic view works better. I needed a way to switch from one view to the other without resorting to View menu > Layout. Maximize Message Pane cannot restore the vertical view. Layout Button works perfectly.

This review is for a previous version of the add-on (1.2).
