A tool container can contain all the extra tools you have in a single item slot.
A bottomless bottle can contain a large amount of fluid inside a single item slot.
A bottomless shelf can hold 6 bottomless bundles and bottles inside a single block, and remember the items and fluids they held, allowing for easy filtering.
