I've been working on a SKSE cell based inventory inventory system for the last couple months, The bare version I made, which just pushes object into a container without care for item type, works as intended. Adds new item to the container, if the container has enough cells but no free space for the item then it sorts the container to try and make room. So I plan on continuing with it further now and write down my current plans for it here.
