If the game adds "more inventory tables" I am sure we will not obtain the desired effect, because the "garbage" will be more difficult to locate and thrown away/sold, and this is exactly what I miss.
It also seems to me that the work done between shadowbringer and endwalker has been forgotten: SE removed the "HQ crafting items" (+rebalancing the difficulty of the recipes), effectively eliminating many gathering items that took up inventory space.
What I'd like to see is some visual indicator of the difficulty of obtaining a certain item, white-green-pink-blue-yellow, AND a more rational sorting.

What matters is not the size but how it is used.
