Hello Shaun!
I know you said: Little Fingers is offered free, as-is. I won’t be offering support or taking feature requests. That said, I hope Little Fingers treats you well.
But if you can, consider just update the code to recent version. I downloaded the code to rebuild in swift but I'm in macOS Monterey and the version of the build/code is not supported, it asks Xcode 10 and, unfortunately, Xcode 10 is not supported in macOS Monterey. So, the app is not working and I can rebuild it haha.
If you can, just update the code for compatibility, I can do the rest.
Thanks!
