What is new in Quill 0.2.0

Quill 0.2 opens any folder as a writing space, reads Obsidian notes as Obsidian shows them, and makes typing faster.

## Install

1. Download `Quill.dmg` below.
2. Open it and drag Quill into Applications.
3. Open Quill. It needs macOS 26 or later.

Apple notarized this build, so Gatekeeper opens it with no warning.

## In this release

- **A window for any folder.** Press ⌘O, drop a folder on the Dock icon, or run `quill .` in a terminal. The co-writer uses that folder as its context.
- **Obsidian syntax.** Callouts, `![[embeds]]` of notes, headings and images, properties, math, `%%comments%%`, and block ids show as Obsidian shows them.
- **Mermaid diagrams.** A `mermaid` code block draws as you type. If the diagram breaks, Quill keeps the last drawing that worked.
- **Faster typing.** In a 92,000-character note, a keystroke takes 1.6 ms instead of 2.8 ms in 0.1. In a note full of Obsidian syntax, it takes 1.5 ms instead of 4.6 ms. Notes open at the line where you left them.
- **Big folders stay responsive.** Quill finds notes in the background. Changes to files that are not notes, such as build output, no longer slow the window.
- **Hanging indents.** Wrapped lines in lists, quotes, and callouts line up under their text.
- **A new first run.** The opening draws the Q in glass over a night horizon.
