#8 Edit element from the tree view

[jslarochelle]

Because it is not always easy to find the correct element to select for mouse "left clicking" in the right panel it would be nice (and probably easy to implement) if we could get the little Element attribute editor to pop-up from the tree tab. The nodes in the tree view show attribute information that can really help locate the right element to edit specially when a lot of element have the same name and vary only by their attribute.
