Notes that flow.

A light text editor for taking notes, that still opens any text or code file. The simplicity of Notepad++, the customization of Vim, a modern interface.

Typing a note: each indented line gets its connector

Indent, and the ideas connect

Press Tab when a line follows from the one above: Cascades draws the link. The file only holds tabs, the lines are drawn, never written, so your notes stay plain text that opens anywhere.

Made for writing

Smart lists, auto pairs, case and line tools, spell checking, bookmarks, and the lines changed since the last save marked in the margin.

All your notes at hand

Folders on the left, quick open with Ctrl+P, search and replace in every file. Tabs, split views, and a session that comes back as you left it, unsaved notes included.

Only the text

Zen mode hides everything but your words. Seven themes, light and dark, and your own.

See it rendered

Markdown, HTML, CSV and JSON previews next to the text. Images and PDF files open in a tab.

Yours to shape

Every setting and every shortcut in one window, or in settings.json. A leader key for more shortcuts, and everything is a command.

Plugins

A plugin is a folder with a manifest and a JavaScript file. It gets the same API as the features built into Cascades: commands, shortcuts, menus, panels, the editor.

Write a plugin

export default function (ctx) {
  ctx.commands.register('hello.say', () => ctx.dialogs.alert('Hello'), {
    title: 'Say hello',
  });
  ctx.keybindings.register({ key: 'Leader H', command: 'hello.say' });
}
