Suggestion...
Would it be possble that : In the display screen, when one clicks an object, the source code related
to that object be hilighted immediately.
Not that I am requesting a copy of the beautiful sharePointDesigner, but...
A good example of this would be Live View in Dreamweaver CS4 which allows you to click or highlight text in the preview pane so it jumps to and highlights the same text in the code view pane. I much prefer WebBuilder to CS4 for code editing, so having this feature would really speed up the working process, especially as relates to editing text and quickly finding elements on the page.
