TL;DR
Add an optional description when making/editing blueprints so that more information can be stored about the blueprint than just a title.What ?
In the blueprint menu for creating a blueprint, add a section where some notes about the blueprint can be stored. This seems like it would be easy to do because it only adds a text box to a pre-established GUI.Why ?
This would drastically help the easy reproduction of blueprints that are downloaded or unfamiliar. For example, the description could save stats on how much material is used per minute or how much the blueprint produces.The screenshot specifically shows the main case for how helpful this would be. There are four lanes of incoming material, but the blueprint won't tell the player what material is in each lane. When you place down the blueprint, you have to connect the transport belts to the correct lanes. This could be done in the description or you could add icons like you can on the map view.
