I hear ya. From gathering items to use for crafting, my gear as well as misc things, my retainers and inventory are at their max. And unfortunately I am stuck selling things I wanted to hold on to for future crafting ingredients. I know housing is still up in the air with what you can actually have furniture wise, but maybe depending on how affordable and convenient it is there will be pieces you can craft/buy to hold more items. Assuming housing is even affordable.
