Quality Assurance (Shorthand QA) is a mod which adds multiple things related to quality. This includes:

• Base Quality - Adds quality to machines automatically, as if a quality module was added.
• Early Quality Unlock - Enables all qualities to be unlocked at the quality module technology.
• AMS Machines - Adds new machines which have additional module slots. These are slower than their normal counterparts, but the extra module slots are worth it.
• Improving Quality Modules - Multiplies the quality effect of all quality modules, so you don't need to wait extremely long to get your high-quality items.
• Quality Modules in Beacons - Allows you to place Quality Modules in beacons.
• Everything is configurable - Most likely the best feature of the mod, all of the above features are fully configurable, or at least they should be.

If you encounter any issues, please turn on dev mode, load up the game and then send me a helpful message describing the issue as well as the factorio log file (can be uploaded anyway).
