Notable provides a very powerful Markdown editor, it's the same one VS Code uses in fact, so features like multi-cursors, a minimap and best-in-class syntax highlighting are built-in.
Notes and attachments are simply stored on your disk, this is extremely portable and powerful: you could edit your notes via a third-party editor on mobile, have them synchronized via Dropbox, use Git, run a regex-based search and replace etc.
A dark theme is also available. In the future support for custom themes will be added as well.
Zen mode provides a minimalistic editing and reading experience, hiding everything that's not necessary.
A multi-note editor is available for performing an action, like favoriting, pinning, deleting, tagging etc., on multiple notes at once.
A split-editor is available for quickly checking out how your note will be rendered while you're editing it.
Built-in cheatsheet for quick reference.
Built-in tutorial for learning the app while using it.
Multiple data directories are supported, so you can separately store different notes collections.
Attachments can be added to any note, even via copy/paste, and they are also stored on disk individually.
Tags are indefinitely nestable.
Import your existing notes library from other apps like Evernote or Boostnote.
Export your notes to Markdown, HTML or PDF.
