Notes
Notes is a library plus sticky notes you pin onto pages. Tag: Productivity.
Turn it on
Menu → Settings, or go to stealth://settings. Click Power Ups in the left list.
Find Notes and click Add. Or click Full Power to enable the whole catalog at once.
Settings → Toolbar. Drag the PowerUp onto the toolbar if you want a one-click button. Each PowerUp can also be paused with site protection from the Stealth logo.
How to use it
Click the Notes toolbar button. The library holds every note, not just the current page.
Pin a sticky onto the page you are looking at. It stays on that site until you remove it.
Type in the sticky or open the same note from the library.
Notes stay in this profile. They are not uploaded. Offline Page is the tool for saving a full page copy. Clipboard History is for copies you make elsewhere.
