See reference popup when I wait over item in the designer

Why not show a See reference popup when I wait over an item in the designer? Now I have to see what type the item is (say I’m seeing some other’s design) and do that action at the toolbox after I spot the item there

at the property editor there is only a video shown with ?, maybe that could show a see reference popup over the ? button, right after the video finishes, or even appearing at the same time as the video popup (if you can show two popups at a time that is)
