Release notes:
Improved the full screen display (slideshow) of directories and archives. A slider has been added to the controller so that you can freely jump to any position. Moreover, you can now see the keyboard assignments for functions in Help. In addition, fixed the problems that WebP images are not displayed and that the marked files cannot be deleted.
