There so many more items in the game compared to when the game was first released - probably twice as many, my guess. Maybe more. (I’m sure someone can chime in here with an exact number)
We’ve been begging for inventory space forever, but it’s getting more and more necessary, and has gotten to the point that it’s becoming a pretty sizable obstacle to building.
I propose starting small - add one more row of inventory space. There’s room on-screen and there is a huge need.
I think it would be neat to go even further - everyone gets one free extra row, but you can craft and buy a single equippable backpack of various inventory capacities depending on quality, give us something to trade. Or do something like in ESO where you can buy one inventory slot per day from a vendor, to give people a daily-play reward (something that is pretty lacking in boundless).
