03 / Browser extensions
Small extensions that tune familiar web services to the amount and kind of information you want to see.
04 / Principles
Familiarity over novelty. Direct control over oversized systems. Software should earn its place in your daily rhythm.
Keyboard and direct manipulation come first, keeping the route between intention and result short.
Files and input stay under your control. Local processing is preferred whenever it makes sense.
Settings, logs, and source remain open so that people can understand the behavior and make informed choices.
