Thanks for sharing such a great system. it's been working smoothly with the mouse, hover, and drag functions.

I'm trying to adapt it to also work with a keyboard, gamepad, or controller, along with the mouse. I'm having trouble accessing the items in the WBP_Hotbar UGridPanel_Items variable and figuring out how to manipulate the widget elements properties.

Could you guide me on how to implement navigation through the inventory using the keyboard's arrow keys and change the background color of the selected item? I'd be happy to make these changes and push the updated code to the repository.
