NewTabPad

A Chrome extension that replaces the new tab page with a plain-text notepad.

Features

• Multiple notes with auto-save (500ms debounce)
• Line numbers with overflow indicator (›) for lines exceeding the visible width
• Syncs across tabs in real time
• Safe during Japanese IME input — updates from other tabs are held until composition ends
• No build step — plain HTML / CSS / ES Modules
