We need a special late industrial storage container for building materials / minerals. It must have huge capacity compared to lockers and use only a base-wide inventory system. consider that building costs in Subnautica 2 can already be something like 0.25 glass, so why should late game storage even bother with inventory slots logic at all? Besides, crafting materials are now pulled from all storages in a base so effectively the base has only a single inventory anyway. For the late game and especially for building materials we need a storage solution that displays the total material available in stacks: Titianium: 26.5 / 100 Titanium, Copper: … . And unlike lockers these should be directly linked to each other forming a single inventory - so it does no longer matter where you put your stuff. But it should be exclusive for materials: e.g. metals, quartz, but not components like copper wire, not for consumables nor equipment and tools (those would still need lockers). Total capacity would grow with each additional container build.
Furthermore it should be both an interior and exterior module at the same time. Placed onto room-walls, it would mostly be build on the outside but with an interior access port and another exterior one. Exterior acces would serve for vehicle docking to load/unload and haul large amound of resources between bases.
It would also visually break-up empty walls (both interior and exterior) and give us more reason to build larger bases, which then require more mineral harvesting, thus more gameplay.
Limited base inventory and annoying inventory management was one of the few things that never was fun in Subnautica games and it discourages me from building more then absolutely neccessary.

True. A huge storage container that is limited to holding one type of item but then a LOT of it would be really cool.
I mean, we need a LOT of Titan, Copper and other ressources, and it already happened to me, that i have SEVEN wall lockers full of Titan and i’m about to build number 8.
