  • Transparent desktop floating windows: Sticky notes, todos, calendar, schedule, and weather/time can all be embedded transparently on the desktop (mobile platforms use fixed-area widgets, not floating windows)
  • Multi-widget stacking: Place multiple desktop widgets simultaneously, each displaying a different list (go to SettingsApp Settings to control the count)
  • Desktop widget style customization: Opacity, background color, font, font size, margins, line spacing
  • Data export: Export all todos and sticky notes (including deleted ones)
  • Shortcut keys: Show/hide all boards, create new todo, lock/unlock boards, sync data, voice input for todos (all customizable)

All platforms support adding todo, sticky note, schedule, and countdown widgets to the phone’s home screen — no need to open the app.
