Confusing Items Keys and Possible Solution

Topic of Concern: With the new updates, grenades are now added into the game and two of the same items can be picked up. These changes cause some of the items to be placed into the inventory boxes (1, 2, Q, E) that would normally hold other items, upon being picked up.

How This Affects Gameplay: Many players are used to each of the four collectible items having its own key. With the new mechanism, it's hard to use the items without taking the time to look at which items are held in what boxes. This makes it difficult to efficiently fight during battle, especially during 1v1's when timing is everything.

Here's a Possible Solution:

1. Add new inventory boxes for the new items (maybe use the 3 and 4 keys?).

2. Instead of holding a second potion, knife, bomb, etc. in another box, put a small number under the box that was originally assigned to them to indicate the number of that item the player is carrying. Examples shown below (Excuse my inadequate demonstration skill):

maybe use:
