agalwood/Motrix ? reverse-engineered prompt

Build me a simple but full-featured download manager app for Windows, macOS, and Linux that supports downloading files using regular links, as well as torrent and magnet links. I want it to have a clean and easy-to-use interface where I can add downloads, see their progress, control speed limits, and select which files to grab from torrents. It should let me manage multiple downloads at once, get notifications when files are done, and be able to pause, resume, or remove downloads as needed. I’d also like automatic tracker updates for torrents, support for different languages, dark mode, a tray icon for quick access, and handy options to organize or delete files when removing tasks. Look up any details you’re unsure about in the project’s website or docs.
