Ability to view who favourited your post or followed you recently in a pop-up box

I’d like it if we could have something similar to FLICKR, where “__ and 12 others faved __” with the “12 others” being a bold, clickable section that brings up a pop-up box, in which you can see all the profile pictures and names of each person that followed you or favourited your post, with a button next to each indicating whether or not you follow them. FLICKR has this:

At the moment, you have to hover over each person's small profile picture in your notifications to see this, but a pop-up list would be much faster to view or skim. I also think there’s a limit to how many people’s profiles can be listed in a single notification (but don’t quote me on that!).
