gThumb 3.8.2 Released! Menu in Top Panel Merged to Headbar

Last updated: November 21, 2019

Gnome image viewer and organizer gThumb 3.8.2 was released a few days ago with app menu improvements. Here’s how to install it in Ubuntu 18.04 and higher.

gThumb 3.8.2 uses menu instead of popovers for menu buttons on the header bar, so the drop-down menu now has icons, and accelerator keys.

Gnome shows focused application’s icon and name with a drop-down menu in the top panel. In gThumb 3.8.2, the top panel app menu options are merged into the header bar menu button.

The new release also improved webp support. You can now open webp image from files’ context menu (‘Open With Other Application’). Or simply set gThumb as default image viewer to open webp in file’s Properties dialog (‘Open With’ tab.).

gThumb 3.8.2 changelog:

  • Use menus instead of popovers for menu buttons on the header bar.
  • Align menus to the right for menu buttons on the right side.
  • Search: show the matching files during the search operation.
  • Rename dialog: activate on enter.
  • Added image/webp support in .desktop file.
  • Translation updates and some bug-fixes.
