Does it bother you having multiple random incomplete stacks of the same items laying around? Well it does me. I made this for my OCD and figured I can't be the only one out there.
Uses Vanilla Mechanics.
Changes the priority of merging stacks to be done first before all the other hauling jobs. If you have a large base and multiple stockpiles this may delay your normal operations until things are merged but once it's all merged the upkeep should be minimal.
Enjoy!
Should be compatible with -EVERYTHING- as this only changes priority and not base game functions.
