In case you don’t know about Sushi, it’s a macOS Finder’s Quick Look style application, allowing user to press Space<\/b> key to get a quick preview of files in Nautilus (aka GNOME Files), and press again to quit.<\/p>\n

It’s a 14 years old GNOME Project<\/a>, which was discontinued a few years ago due to lack of maintainers. One of GNOME Files maintainer revived the project several months ago and released version 50.<\/p>\n

With the new 51 development release, it’s finally ported to GTK4 + LibAdwaita<\/b> that looks modern and native in recent GNOME Desktop releases.<\/p>\n

It now automatically switches between light<\/em> and dark<\/em> style according to your desktop color scheme.<\/p>\n

And, the video preview support single click to pause\/resume playback, and double-click to maximize and restore preview window, while, a maximize icon is also available in header bar.<\/p>\n

The new version also added double-click support, along with a header bar icon, allowing to maximize or restore the window when previewing photo images.<\/p>\n

For HTML preview, it now prompts “Remote content is blocked to protect your privacy<\/i>” when you clicking on a remote content, such as a URL. Though, user may right-click on URL to select open in web browser or copy the link.<\/p>\n
