I installed the mod, but I don't have a "Chest Merge Tool" in my Blueprint library. I see from an earlier post that the Chest Merge Tool is now obsolete, but I don't understand what has replaced it. How does this mod work now?
Oh, I figured it out. There is a button near the bottom of the screen, to the right of the inventory area. It is a grey button that is decorated with an "M" with a square around it. Click that button to merge chests.
