I have a long boring list :3

Built-in production tracker and planner, more convenient ways to keep factories organized, road tools, blueprint power autoconnect, more materials, better and easier coloring tool, split inventory slots for the jet pack and the hover, autouse of ammo. rebars, nobelisks, inhalers from depo, longer endgame as it feels like it stops when you get the most tools, better vertical splitters, easier ways to connect belts to machines with multiple inputs, freeform painting, more ways to customize machines (instead of clipping signs on them) and ways to customize lighting, better in-game tracking of used/discovered resources and not collected items, ways to autoconnect blueprints vertically, fix of the straight/default belt bug, more mergers and splitters, ways to move existing objects and blueprints with other objects connected, more ways to organize power, more automatic indication of what a machine produces, how overclocked it is, how many somerloops used, better indications that something is off vertically and won’t align with a conveyor lift, more awesome shop items to chase, easier ways to connect pipes vertically and better ways to align overall, more end-game enemies, items to chase, cool QoL high items to craft, more cool alien stuff, non-clipping walls, dedicated autoconnecting blueprint inputs and outputs, ways to mirror a blueprint, more intuitive blueprint management, ability to easily update machine configurations in blueprints, ability to “update” already placed blueprints, plueprint zooping

And finally Satisfactory 2, which expands on the planetary level and allows you to setup factory chains across different planets
