Auto research: https://mods.factorio.com/mods/canidae/auto-research
It's like this mod, but with research! Coupled with research savr mod you can also stop the game from pausing when research completes a project without losing any science packs. It picks the cheapest research projects first with customization and pause options.
HotCraft: https://mods.factorio.com/mods/binbinhfr/HotCraft
Use hotkeys to handcraft more of the the item that is in your cursor. For those things you don't want autocrafted but still want to easily craft more of while you place them.
Bluebuild Rewritten: https://mods.factorio.com/mods/gheift/ght-bluebuild
Allows automatic blueprint building and deconstruction without bots. Once a blueprint is placed, nearby entities will be auto-placed as long as you have the objects in your inventory and are standing still.
Great for early game no hassle blueprints. A mod that is as simple and elegant as HH.
Press SHIFT+K to toggle building, press SHIFT+L to toggle deconstruction.
