The plugin author still very active on GitHub (https://github.com/zzeneg). Why don't you ask him? It looks like he made his plugin repo private or deleted it.
What you are asking for isn't terribly difficult; and IIRC, his plugin used C#, and the .NET Clipboard class is pretty extensive.
But anything you could do with a Rainmeter plugin pales in comparison to simply using the built-in Windows clipboard history feature (Win+V). Before Win 10/11 I can see why this would be of interest, but since this is now built into Windows I'm not sure why anyone would bother with trying to kluge up something with Rainmeter.
