So i started using this script and its not to bad. I manly wanted it for the shelter though. I just noticed something and im curious on it. When I look up at the tampermonkey symbol it has number and every time I go to a new page in pokefarm it does up by one. Any idea why? Im just curious if you know. Is there a feature to find pokemon in the shelter with items?
