We split multiple snippets of content on a page out from the layout, into a series of partials. This allows content authors to not get confused/break the design.
To aid content authors in understanding which snippet goes where, it would be great to be able to put a box around a snippet (e.g. when mousing over it), and add a tooltip to show the path to the partial.
It would then be great if the author could click on the area (or perhaps to prevent accidental clicking, or to avoid breaking links, perhaps we make it a ctrl-click or something), and have that area open in the editor.
