[Annoyance, i.e. more than a Nit Pick but less than a Bug]
In the Actions, we have 20 actions to Apply the custom layouts.
But there is no Action to Apply the default layout. The Action "layout: Default layout" just clears the Track Panel (and Mixer panel?) layout in the Layouts window.
I can set a track to its default format form the TCP Context menu, but not from a toolbar button with the "Layout
efault button associated with it.

Also, in the Layouts window, the text "Action #11" to "Action #20" should use the same terminology as in the Actions window, i.e. "Custom layout #01" to "Custom layout #20".
