Given Chests that have item frames on them, render the item in the item frame instead of the chest icon

Ooh, I really like this idea. I'll look into implementing it in the future. For now, you can rename your inventories to get a slightly similar effect

I've started work on this feature. Right now, putting an item in an item frame near a chest will now display that item on the tab, but the item frame detection isn't the most efficient and it can only detect item frames if they are spaced out a little.

I've refined the item frame detection down and gotten this feature working for double chest hitboxes!

It is in release 0.8.1.

Yeah, that was intentional. Wasn't sure what icon to use (item frame item, regular chest, no icon, etc), so I just left it use the result of ItemFrameEntity.getHeldItemStack(). Is there something you'd rather the icon be?

Empty item frames make chests not have an icon at all?

Just felt a bit odd, maybe later on add an option to show it as a chest?

Yeah I can change it to do that. Didn't imagine anyone would use empty item frames on a chest, haha
