When you are standing near more than one item, a blue glow appears around all of them.
When you press enter, you get a pop-up to select one. Unfortunately, when the pop-up appears, the blue glow disappears, and if you are selecting from more than one identical item, it can be really hard to tell which is which.
This could be made a lot easier if a blue glow appeared around just the one you are about to select from the pop-up. This would be particularly helpful with animals which wander around.
