There are often cases when elements are placed on a page, sometimes for experimentation sometimes to wire up other elements (e.g. dataset), but get lost or hidden. It would be very helpful (especially on a busy layered page) to have a drop down on a page in the editor that lists all of the elements that are on the page so that the one you are looking for can quickly be located.
This is sort of doable in the code editor screen by autoComplete when you type $w(...
However it can be cumbersome to have to keep opening the code page to find elements. Since auto complete already finds all on page elements this (hopefully) should be a straight forward request?
