I think it would be a good idea to show the user how the attributes for items are being created. I've got a complicated XUL document, loaded into the Penzilla environment, and I want to get the height of a body element inside an IFRAME. I can use the dom inspector to get the height, but I don't know in my code how to get that value. It would be nice to be able to right click and see an option View Code that would show me the code it used to get that value.
I think this bug is a little too finicky: For one thing, we don't know what language the user is in. If you don't know how to do something, then either don't do it, or learn. But don't rely on a program to tell you how because there is no guarantee that the program's output will work for you (due to scoping or placement) or the output may result in inefficient code (e.g. you may have a reference to an element already but the output will have to assume you don't and thus may output code which walks the document tree in order to get to the element). I suggest you learn about getComputedStyle() which will answer your question as to how we arrived at the height. And I suggest marking this bug as WONTFIX.
Marking as such.
