Shiny throught slots are well but 9 slots would be better for me 6 is not enought.
Chat disappear too fast
New messages should stay longer on chat like 1minute not 5s
Sometimes killing mobs or fight take much time so is hard to notice everythink in 5s.
I think that would throw off the controls becase the action button and d-pad are about the same size and the idea of a 3×3 would not stay in that little rectangular space on side unless you made the quick slots smaller because the backpack and crafting take up a good amount of space
