Markdown01 per ntrezowan

Markdown01 is a lightweight, sidebar-first Markdown editor designed for platform engineers, DevOps users, and anyone who wants a fast, distraction-free writing experience directly inside Firefox.

Unlike full-featured editors that try to do everything and end up slowing you down, Markdown01 focuses on speed, clarity, and reliability. Everything stays local, there is no telemetry, and the UI is intentionally minimal so you can focus on writing.

Key Features

• Sidebar-only editor (no new tabs or popups)
• Instant toggle between editor and preview (Cmd/Ctrl + E)
• Autosaved drafts stored locally in Firefox storage
• Timestamp-based filenames for fast note creation
• Export Markdown files directly to Downloads/Markdown01
• Clean preview mode optimized for readability (14px baseline text)
• Lightweight syntax highlighting for:
• bash / sh / shell
• json
• yaml / yml
• env files
• conf / ini / cfg
• Firefox-native light/dark theme support
• Pinned toolbar icon toggles sidebar open/close
• Zero telemetry, zero external dependencies

Why This Exists

Most Markdown tools are over-engineered for quick operational work.

When you are:
- troubleshooting systems
- writing runbooks
- capturing terminal output
- documenting infrastructure changes

You do not need plugins, cloud sync, or heavy rendering engines.

You need something that:
- opens instantly
- never lags
- never sends data anywhere
- works offline

Markdown01 is built exactly for that.

Storage and Privacy

All content is stored locally using Firefox extension storage.

When you export, files are written to:

Downloads/Markdown01/

No data is sent externally.
No accounts are required.
No tracking scripts are included.

Limitations (Intentional)

• Not a full IDE
• Not a collaborative editor
• Not meant for large documents with heavy formatting

This is a focused tool for fast, local Markdown usage.
