1) When blueprints are made in the alchemy workshop they will be stored in your civilization's inventory. From the inventory, you can open each of the 4 types of blueprints for a chance to unlock a building or piece of gear associated with these blueprint types (opening a basic blueprint can unlock a basic building). When a villager picks up a blueprint and deposits it at the town center this process is automatic, and will unlock a building/gear if it has not already been unlocked. If it  has already been unlocked it will be converted into blueprint dust which can be converted into blueprints at the alchemy workshop.

2) When a character is moving it can be difficult to keep the cursor on the profession select box which will display a popup with information on the profession. Thus, I have expanded the touch box in which this can occur to make it easier to see the profession info, especially when a character is moving.
