The inventory isn’t complete, it’s just the overall design of which label goes where.
The item slots are a viewport frame of the item. It is parented under a scrolling frame.
The top bar that says “All Materials Weapons Weapons Weapons Weapons Weapons” are the filters. They are a horizontal scrolling frame
(They will eventually be labelled as different filters with a different icon)
The inventory covers almost the whole screen.
All UI positions are fixed.
So just looking at the overall design, what can be improved? (You can still suggest a change of positions for the ui if its too horrible)
