Build me a simple Mac app for developers that works like a scratchpad for quick text fixes and little utilities. I want to be able to paste in text, run small scripts on it, and see the result right away, so it feels easy for everyday stuff like cleaning up text, formatting code snippets, or making repetitive edits faster.

Please make it feel polished and native on macOS, with a clean editor style interface and a way to browse or run built in scripts plus custom ones. It should be easy to add new scripts without rebuilding the app, and there should be clear documentation for how to use and extend it. If you need to look up current Apple or macOS docs online, go ahead.

Keep the experience focused on speed and simplicity, since this is meant to be a handy developer tool people can open, paste into, and get work done quickly.
