I've noted that more than one instance of Reference book can be opened. Whenever the Help=>Reference book is selected another instance of the book is opened. Not a problematic issue - but it might be if someone gets to open lots of them. What do you think to have only one instance allowed?

What do you think to change the equal sign (numerical equal to - "=" ) into the Boolean equal to. At the moment, copying a region from the Reference book into the Worksheet will produce dissapearing of the RHS (Hmm..., I wonder how the numerical "=" can resist in the Reference book?) . When copying from the Reference book into the Worksheet with Boolean equal to, this way the math region will be preserved.
