When adding media to page/post using the "Add Media" button, the "Insert Media" panel pops up.
This shows the list of images in the Media Library.
When looking for the correct item to add (when there are lots), it would be VERY helpful if the image file name or title was displayed on mouseover.
This would be useful for site currently building which has images of 150+ pairs of scissors - which all look very similar in thumbnail size.
Even using the search doesn't narrow the selection enough to be really useful. The mouseover effect would be great!
