Every time I think I can't like Storage Drawers any more, it goes and proves me wrong...The "Storage Drawers" mod also has a "unify" feature built-in, and it is very nice to have. Simply create a Storage Drawer and insert your preferred ingot type, for instance, Thermal Expansion (TE) Lead Ingot. Do not have a Storage Drawer with any other type of Lead Ingot. Now, every time ANY type of lead ingot comes into the Drawer Controller, the mod will automatically convert it and put it into the TE Storage Drawer. It works with other item as well, its not just limited to ingots (such as IC2 dusts and TE pulverized materials being equivalents).
If you don't want certain items to be "unified" - a good example being IC2 Rubber and MFR Rubber Bars, which each have their own uses - then just create a Storage Drawer for each item, and the mod will route those items into their respective Drawers without converting them.
For us "neat freaks", having the Unify feature built-in and requiring no work on the part of the player, it's an invaluable asset that makes Storage Drawers an almost 'must-have' mod for early game base organization.
Yes, you'll need a drawer (or drawer slot) for each unique item you want. However, that's no different than barrels, and organization/automation is FAR easier with drawers. One storage bus is all it takes...
