Janus is a simple, native linux text editor. Supports UTF-8 and binary data through its fallback binary editing mode. Spiritual successor to leafpad. Intended to be as small and efficient as possible, trading features for a smaller impact on cpu.
Features include:
- Undo/redo
- Similar keybinds to other text editors (e.g. leafpad)
- Spanish/French/German Translations
- Printing capabilities
- Optional syntax highlighting
- Fallback binary editing
- GVFS connectivity
