Show Renamed Item Names When Hovering Over Items in the Shelf Block

After renaming and placing an item on a shelf, I suggest that you should be able to see the item's name when you hover over it with your cursor.
Why should this feature be added?

Currently, you cannot differentiate between two items that look the same because of the way the shelves work. For example, if you have a diamond shovel enchanted with Silk Touch and another with Fortune, there is no way to tell them apart when they are on the shelf, even if they have two different names.
With my suggestion, however, you could easily differentiate between the two.

Second, it would provide an easier, more compact, and lag-friendly way to display your custom items other than item frames. This would be a good addition to make shelves even better.

Lastly, this would add more decorative and utility options. For example, you could make elevators with green and red wool and rename them "up" and "down." When the player hovers over the green wool, it would tell him to go up.
There are many more possibilities than just that one example; it would give players more creative freedom.
