GNOME Sushi as the file previewer component for the GNOME Files (Nautilus) file manager has now been adapted to make use of GTK4 as well as delivering other enhancements for a nicer file previewing experience on GNOME.

The GNOME previewer companion to Nautilus has now been adapted to make use of the GTK4 toolkit as well as initial Blueprint and Glycin usage too. Some nice enhancements to Sushi for the current GNOME 51 cycle. I tried it out on the GNOME OS Nightly build.

Plus there is now initial dark mode support, nicer floating toolbars, and other clean-ups. The layout of several file type previewers has also been enhanced.

More details on these latest improvements to the GNOME File Previewer along with other updated GNOME software components can be found via the latest issue of This Week in GNOME .
