InvidiaTweaks is a growing collection of Factorio gameplay and quality-of-life additions, starting with a full underground layer system. Build across 10 underground floors, route items and fluids vertically between layers, transfer power between floors, and use rail-based power nodes to carry electricity across connected rail networks.
The mod also includes an extended research queue with a dedicated management interface, science-pack filtering, manual queue planning beyond the vanilla limit, and optional auto-research when your queue runs dry. More tweaks and systems will be added over time under the same mod.
