Notes that arrive with the sentence they belong to

On a wide screen each note sits in the margin beside its line. On a phone it opens right under the paragraph. Hover a number and its note lights up.

How a sidenote reads

Every tool decides how expensive a mistake should be. Most of them decide badly.1 The undo button is the kindest thing a piece of software does, and it is almost always hidden2 behind a gesture nobody was taught. I started keeping a list of the places where a margin would have helped3 instead of a modal.

  • 1Badly means: late, loud, or not at all.
  • 2Cmd-Z lives in the head of the person who learned it in 1996.
  • 3A note in the margin interrupts nothing; a modal interrupts everything.

From grid paper to page

Every essay starts on grid paper, by hand, in pencil. The first draft is mostly arrows.1 I only type it when the argument fits on one page2, then send it to two friends who are allowed to be rude. The notes come last3, once I know what the sentence was trying not to say, and the margin gets the doubts4.

  • 1Arrows are cheap. They show where one idea leans on another.
  • 2If it needs two pages, it is two essays.
  • 3Tom and Inês, who disagree about almost everything.
  • 4A doubt in the margin is honest. A doubt in the body is hedging.

What I am reading, and what I wrote in the margins

1The Humane Interface, Jef Raskin. Reread this spring. The chapter on modes is still the best argument against the settings page.
