The new version of Drafts for iOS and iPad OS is really nice. It adds a lot of new features:

Rewritten main user interface and gesture interface.
Support for multiple windows (iPadOS 13 only).
Edit actions in separate window.
Live Markdown previews in a separate window.
Automatic dark and light mode switching (iOS 13 only).
Contextual menus where appropriate throughout the app (iOS 13 only).
New Quick Capture action extension.
Live Markdown previews (iPadOS 13 only).
Support for new iOS 13 font selection panels.

The Shortcuts support is extensive with many new actions. I'm sure there was a ton of work in all these changes. As a subscriber, I'm definitely getting a bang for my buck.
