Ever found yourself going through the item tab trying to find combinators, lamps or walls from amongst the belts, inserters, assemblers and hand grenades? This mod adds a layer of organisation to the crafting tab, as well as your inventory if it's automatically sorted.
This adds a new tab, called "Construction", that contains the stuff that don't have anything to do with logistics or production, but rather a part of your base infrastructure. The combinators, lamps, walls and concrete are moved here.
The mod also attempts to move other modded stuff into the new tab. If for any reason you have other mods that add a ton of terrains, this mod also makes another tab, called "Terrain", and moves the terrains there instead of Construction.
Note: it's all heuristics though, so it may produce weird results. Expect the mod to update and, when used with big mods, to bring changes to the tab layout when it does!
