Atlas: Write and Collect 1.1.0 is a meaty release with a focus on Customization of the editor and easing the collection of external items!
Custom Theme Editor

Create your own editor themes with a full three-column Theme Editor. Customize colors, fonts, and styles for every markdown element — headings, bold, italic, lists, code blocks, links, and more. Edit light and dark appearances independently with a live preview that updates in real time. Use the Quick Color palette to define reusable colors that cascade across linked elements, making it easy to restyle your entire theme at once. Choose from three color picker modes — Grid, Spectrum, and Sliders — with support for HSB, HSL, RGB, CMYK color spaces and hex input.
Theme Import & Export
Share your custom themes as `.atlastheme` files, or import themes from others. Atlas also supports importing Ulysses `.ultheme` files, automatically converting them to Atlas themes.
Theme Sync
Custom themes now sync across all your devices via iCloud. Create a theme on your Mac and it appears on your iPad and iPhone automatically.
Resizable Images
Resize images directly in the editor context clicking an image, enabling resize, and dragging the handle. Set a default image display size in Settings to control how large new images appear when alone on a single line.
Share Extension (iOS)
Share content from Safari, Notes, and other apps directly into your Atlas projects using the iOS Share Sheet. Atlas automatically extracts titles from shared URLs.

New Built-In Themes
Two new built-in themes — Oolong and Birds of Paradise — join the existing collection. The previous Compact and Spacious size-only themes have been retired.
