Never played the game. Do you click on the items to use them? Or use keyboard buttons?
If anyone decides to make a plugin for this then that'll be great. But for the time being, if you like making your own systems, you can use a method that I use. You can use orange hud to show a bunch of variable icons anywhere on the screen. And use a parallel event to navigate through those items if you check for a specific button press like <>. If nobody gives a response, I could try to make a system like this tomorrow. It's fun to event stuff like this ^^
