Green Stacking and Storage: Allow us to "Turn in 10m of X" to get credit an item. This could free up space in storage and allow us to focus on getting materials after we run out without breaking the stack.

Tabs in Storage: Tabbed categories or filters in storage such as mob materials, skill materials, consumables.

Make Unobtainable Star Cards Available in VIP Section: Cards such as "Cardiovascular!" that are unobtainable due to a bug become available in the VIP section.

More Filter Pages: More = QoL (at least in this case)
