I've been making changes to administration form templates for MovableType blogging software. Well, in order to make a change you first have to figure out the existing form and which fields in the HTML show up where in the rendered page. It would be nice to be able to right click over a control and see that control's NAME and other tag fields. Basically, make it easier to find the underlying location in the HTML that is responsible for a given location on the rendered form. Mozilla has a Properties option. But it doesn't tell the control name and it doesn't for instance say that it is a TEXTAREA control. Instead it gives a DOM element name of HTMLInputElement. Not so helpful.

Another thing that would be nice would be traceability back from the HTML to whatever CSS tags are being used to set attributes of the given control or screen area.
