The quick slot bar needs a rework. I want like 8 or 9 slots. The 6 limit just isn't enough. But then it needs to be reworked to make that number usable.
My phone is so damn tall that I think having two rows of slots would be fine. And the gap should be eliminated. I understand how people who play in landscape orientation wouldn't want that, though.
I wonder if a horizontal scrolling quick slot bar would work.
(Yes, I know you can long press the backpack for a huge quick menu, but that's too huge, and everything runs together. Maybe if the items were grouped by type with space in between it would be better. Plus the long press honestly takes too long.)
