If I'm getting your question correctly, you would like to have the Code view in Muse besides being able to edit a page in Design mode (something similar to what Dreamweaver does).
However, currently this feature is not supported. The purpose of Adobe Muse software is to create websites without writing code and having advanced features like this from Dreamweaver defeats Muse's sole purpose.
But I would suggest having this feature request posted over at our Ideas section.
No, I'm not looking for a Code view. Something which indicates the depth of nesting of any given (or at least the selected) element. [I understand the goal of Muse, but even w/o writing code, you still need to be able to visualize the structure of the page]
There are a couple of places in the Katie's Coffee tutorial where it's pointed out that it is 'tricky' to know if you have the appropriate container selected when dropping an image. This would be easy to avoid with some sort of diagram of the page structure - or at least a bread-crumb - which I suggested in the ideas forum: http://forums.adobe.com/ideas/1517
Does this help?
I doubt that Muse could show this structure easily. The layout that we observe in design view is not really structured as it will be when exported as HTML. Muse appears to determine where to create divs only at HTML export. A slight tweak in design view can drastically change the way that divs are created between different HTML exports. It seems that the only way to control this automatic div generation is to use grouping of objects while in design view.
It might be neat to see Muse offer this type of view to understand how the page is structured...
That's a nice view of a page, but it's probably too detailed to be useful while editing. It is really good for visualizing the natural nesting of HTML elements.
I think the suggestion I made in http://forums.adobe.com/ideas/1517 would be more useful in practice because we are usually focused on the containment relationships of a single object - or collection of elements.
I feel like I'm working somewht blind with the current interface and with only knowing the type of the currently selected thing displayed in the top left corner [the Selection Indicator]. Expanding that into a bread-crumb display would relieve my blindness.
