Describe the solution you'd like
It would be lovely to be able to empty multiple inventory items into their matching Storage Barrels at the same time instead of one Storage Barrel at a time. I understand this function is available with other storage mods (i.e. Storage Drawers’ Controller block) but I think it would be a great addition to this mod. This mod beautifully unifies other features I like from other storage mods (e.g. tiered storage + storage barrels) and I love the subtle texture of the tiers in this mod way more than the others. (An entirely gold or diamond chest doesn’t look as good to me as a wooden chest with a gold or diamond clasp—beautifully done!) With the addition of a Controller feature, this mod would be the holy grail.

If there’s no plan to add this type of feature, I understand. It’s still an amazing mod!

Describe alternatives you've considered
My alternative is to use Storage Containers for larger storage rooms, but yours for smaller or starter storage rooms.

Thank you for your suggestion, but there are enough mods that have such features (Like Storage Drawers). The goal with this mod is to stick as closely to vanilla Minecraft as possible.
