I don’t know if anyone ever played Terraria but there was a piggy bank you could have that was like a chest that you kept in your inventory and could store extra stuff in. So it was like giving up one inventory slot (for the piggy bank) but having a bunch of slots inside that piggy bank for additional garb. Something like that would help immensely.
Sorry for delayed reply, but I found a mod that expands your inventory to 48: https://community.playstarbound.com/threads/bigger-backpack.140870/#post-3253223
