Clipboard Mod for People Playground

- This mod adds a clipboard manager that allows you to switch between previous copy saves. They won't disappear unless you close the game or you click "Clear Clipboard".
- When you copy items, it will be automatically transferred into the clipboard and by clicking B (you can change it in the settings) which will open up the interface. To switch between copies, you just click on them! The one on the first (top left) is the current save you're selecting (which by clicking paste or clicking v will spawn it out).
