flameshot-org/flameshot — reverse-engineered prompt

Build me a simple but powerful desktop screenshot app for Linux, Windows, and macOS. I want it to sit in the system tray, let me start a capture from the tray or a command, drag to select an area, then edit the screenshot right there before saving.

The editor should have the basics people expect, like pencil, line, arrow, rectangle, circle, marker, text, selection, and pixelate for hiding private info. I should be able to copy the image to the clipboard, save it to a folder, choose a delayed capture, capture the full screen, or capture a specific screen. Please include keyboard shortcuts and an easy settings window for colors, appearance, save path, and help tips.

Also add a small command line interface for common actions like opening the capture UI, saving to a custom path, copying to clipboard, and opening config. Use Qt and C++ if that makes sense, and look up current docs online if needed.
