Lightweight “S.s” Text Editor

The goal is to create a clean, reliable text-only editor called “S.s”. It should open instantly, handle large plain-text files without lag, and provide the everyday essentials—new / open / save (with encoding options), fast search-and-replace, unlimited undo-redo, and simple preference settings for font, tab width, and line endings. A distraction-free writing mode and dark/light themes are desirable, yet the overall footprint must stay light so the app feels snappy even on modest hardware. Cross-platform delivery (Windows, macOS, and Linux) in a single code-base is preferred; Electron, Qt, or any other modern toolkit is acceptable as long as you keep startup time low and distribution straightforward. Source code should be cleanly organised and thoroughly commented so future tweaks are easy. When you reply, please share links or screenshots of past work on desktop or in-browser editors you have built or maintained—seeing how you solved performance and usability challenges before will help me choose quickly. Deliverables • Complete project repository with build instructions • Installer or executable for each target OS • Concise user guide covering the main functions I will review builds on both large and small text files; smooth typing, stable memory use, and a polished UI will be the key acceptance criteria.
