Galacticraft looks like a huge and awesome mod, and I think would fit nicely with Thermal series, Tinkers, and Techguns. However their inventory uses the same as yours, so as of now it's not likely I'll use it since I have reaction chamber and everything else of yours already hooked up. They said they refuse to change their mod because of how big it is so I humbly request you find a way to make your tab work maybe slightly differently so to be compatible. Hell if there's a way to tweak it myself I'd be open to that. Now knowing how big an undertaking this would be, it may not be feasible, but it never hurts to ask. Keep up the good work!
