There are times where you can't just work in the styled view.  For 
example, in
MathML you typically have content elements at least nested inside an 
'mrow' element
which is nested inside a 'math' element.  Both 'mrow' and 'math' are 
styled inline and
so, since they have no text content, if you lose the focus on the 
'mrow' element, you
need to switch to the tree view to be able to re-select the element and 
insert content.

In other editors, they give a more compact infoset tree for quick 
navigation or
structure-related issues like the above.  That might be something to 
consider (e.g. a
read-only navigation tree).

"The excellence of grammar as a guide is proportional to the paucity of 
the
inflexions, i.e. to the degree of analysis effected by the language
considered."

Bertrand Russell in a footnote of Principles of Mathematics
