imklydev/myra ? reverse-engineered prompt

Build me a fast, modern code editor called Myra that feels lightweight but polished. I want it to open, edit, and save files smoothly, with tabs for multiple files, easy keyboard shortcuts for common actions like open, save, copy, paste, cut, undo, redo, new tab, and switching between tabs. It should have a clean interface, a file open flow, and basic text editing that feels responsive even with larger files.

Make it highly customizable too, especially the look and feel, with a clear theme system so it can be styled easily. Use the existing assets and keep the app visually unique, not just a plain generic editor. If anything needs current library details or build guidance, look up the latest docs online. I’d like it to be built so it can compile from source with a simple CMake based setup and run well on desktop.
