What I'm looking for is a combination of an tree view outline window and the 
styles to make a Table of Contents that works well for books. The outline 
functions seem to work really well if you're making a numbered outline. What I 
can't seem to find an easy way to do is set up a document and table of contents 
such that the chapter number and title will show up as I create them or assign 
such styles to existing text. I've also seen that Mellel on the Mac has an 
outline tree view that shows me all the ToC entries on the side of the screen 
and makes navigating to particular parts easy. Word has a similar, though less 
elegant window. The problem I have trying to do this with OO is that it doesn't 
take into consideration that a chapter could be called anything other than 
Chapter One, or that the title of said chapter might be worth including in the 
TOC information. Also, the dialog for arranging data in the ToC needs some UI 
improvement, because it's rather obtuse as is. Couldn't it be more like the 
label making process where you have fields that you align like you want them? If 
I could link Styles to Fields and Fields to outline levels, that should be 
enough to arrange a ToC to automatically have everything I need. For a good 
example of what I'd like to see, I do suggest Mellel as it has the cleanest 
implementation I've seen.
