waydabber/BetterDisplay ? reverse-engineered prompt

Build me a powerful menu bar utility for macOS that gives me total control over my connected displays. I'm frustrated with the default system settings and want to unlock the full potential of my monitors.

The app should let me set custom resolutions and enable smooth, flexible HiDPI scaling on any display to make text look crisp, even on non-Retina screens. It needs to handle advanced brightness control, allowing me to push my XDR or HDR display past 100% brightness and also dim any screen completely to black.

I also want the ability to create virtual screens, which I could use for things like remote access or setting up a DIY teleprompter. A picture-in-picture mode to view one display in a window on another would be great too. Basically, it should be a single tool to manage everything from resolution and brightness to display layouts and color profiles, with support for advanced controls like switching monitor inputs. It should work on modern Macs, both Apple Silicon and Intel.
