Game Mechanics Revamped Ingredient pouch

As we know, the main way to carry ingredients is through the ingredient pouch. And while it serves its purpose well for a bit, eventually, it fills, up and becomes frustrating to manage (imo) We should Implement upgrades to the item bag with such increases in capacity, sorting, Ingredient holding. My first idea to implement this would be to do something along the lines of a profession levels. As for the ingredient holding, maybe as you level your combat or gathering skills, you unlock slots for ingredient holding.

This was just a quick thought, but let me know if anyone likes this idea/ would like to expand this or add their thoughts! Thank you for reading.
