Previously Illustrator introduced a way to unlock specific objects under cursor: http://illustrator.uservoice.com/forums/333657/suggestions/34950421

See the screenshot for example.
However, when you have objects unnamed, this list doesn’t really help, and Ai does nothing to highlight the object in focus and help to distinguish from other locked ones.

Ai should make the edge of the object to be unlocked with a thick line, similar to one we see on key objects, or a somewhat similar look it is used for Objects on Path picking mode (now in Beta).

Look how Figma highlights objects (see the attached video).
Why Ai can’t do the same?
