This is a real gem I'm just now discovering. The ways you can upgrade these things is nuts. I'm trying to figure out a few things, mainly in an attempt to design the ultimate mega-backpack, and I'm curious what others might do with it as well, so I can steal your idea for my own. Right now, what I do have with it is already really awesome. I'm playing Sprout, for reference. I have one bag that will automatically pick up everything I mine, but has the 3x3 and 2x2 compacting upgrades, which I can use to automatically turn redstone into redtone blocks on the fly. I will even compress my cobblestone. Not just once but all the way to Quad, which is amazing. I can mine almost forever. I have another with the mod-based auto pickup. Right now, I'm just using it to separate my Silent's Gems gems that get piled up. And lastly, I have the main pack that I've only jsut found out how to equip, which I set to its own button on my controller and added the upgrade that makes it soulbound. This one is full of all my tools and will eventually host my other bags just so they're all on me at all times, just as soon as I figure out how to get a damn egg on this modpack. But, it looks like there's even more potential than that. For starters, there is an option to make a bag upgrade-centric, adding more upgrade points at the expense of storage, but I'm not seeing how I'd ever use that many points? What am I missing here? What neat little things have you done with yours that I could look out for?
