I have to agree the TEXT menus are a bit odd.
IMHO
(because toolbars can not be hidden) they are a a Text replication of a toolbar.
My ideal text menu:
File
Edit
View
Window
Help
Validate belongs on the File menu as it applies to the whole
The current Format and Insert s/b a sub-menu of Edit
Split is a Edit function (I believe it only applies to the current segment)
Book Browser, Validate Results and TOC belong on the Window Menu
Just my 2 cents
I just noted that various toolbars CAN be hidden by a Right click.
IMHO
A toolbar master control should probably added to View
