(this article only applies to Emerald for Mac)

Emerald for Mac allows you to choose between 2 designs for the sidebar and Web Content.

Transparent

This is the default design. The sidebar is transparent and blends in with the Space background while the web content has a bit of padding around it.

Opaque

This design is similar to other macOS apps. The sidebar has a blur background layer and there’s no padding on the web content.

Vertical Toolbar

There’s also a vertical toolbar that shows the website options and details in a compact bar at the top. Website extend behind it, giving it this cool Liquid Glass effect.
