Reset gThumb right panel size to default

Question

Usually right panel with actions takes around 20 percent of the screen. Somehow, now it takes around 70, and takes too much place on the screen. I don't know how it happened (it's my dad's computer) but interested to know how I can reset this setting back to default.

I've tried playing with view menu items, but with no avail.

Answer 1

You can remove its user config files and it will reset back to default view.

rm -rf ~/.gconf/apps/gthumb

and

rm -rf ~/.config/gthumb
