    Just tried and I think it’s still a useless feature.
    You can’t:
    -take full page (scroll) screenshots
    -save screenshots in another format different from .png
    -choose folder to which save screenshots.

      I haven’t tried yet but for me there was an option to take a screenshot of whol3 page (with thebparts that aren’t currently shown in screen included). Yet, I agree with the folder choosing part.
