I like to reduce the player's inventory size by disabling unwanted slots. Then I create a resource pack that replaces all of the container GUI images to cover up the disabled slots.

My understanding is that, because Inmis draws the slots programmatically due to configurable backpack sizes, there is not really an editable container GUI image.

So my question is, would it be possible to add another image here (assets\inmis\textures\gui\backpack_overlay.png) that is, by default, blank/transparent; and then when edited to have an actual image, that image would overlay on top of the slots that are generated?

Screenshot example:

Thanks!
