What is the enhancement in mind? How should it look and feel?

Pay per inventory chest & slot size upgrade button for expanding inventory chest size. Increment of 9 slots per chest upgrade. So a max upgrade of 5 times per inventory chest up to 54 slots with default of first 9 slots included in inventory chest purchased. User can choose to pay a set fee or increment fee for additional inventory chests or slots upgrade. example: inventory_chest.1 cost 100, inventory_chest.2 cost 1000, etc. inventory_slot.upgrade.1 cost 50, inventory_slot.upgrade.2 cost 75, etc.

Please provide any additional information below.
