Keep in mind that P7 seems to "take it's time" because it's actually storing the deleted item in memory. That way, you can hit Undo and bring the item back... yes, that's right- Undo actually works in P7.
In fact, depending on your preference setting, you can undo the deleting of the item even after you've made 10, 20, or 50 changes to your scene.
 
But, yes, like the posters said, P7 still has the "focus" issue where hitting Delete will move you up one Library folder instead of deleting the selected item.
