Here's my current battle screen setup:

And the items screen:

I'd like to move my items into the actor command window. For example, instead of "stab" "acceleration" "item" i would have the following commands: "stab" "acceleration" "heal" "restore". This would mean you don't need the items tab anymore because all of the items are in the actor command window. Is this possible to do? Sorry if my explanation isn't clear ;-;

One thing I tried is using this plugin: here. The problem is that it doesn't have any documentation nor explanation on how to use it so I was unable to add my custom commands to the actor command window.
