I’ve been searching for a program to project slideshows nicely, but I haven’t been able to find anything perfect.
Digikam shows a white background while playing clips (both in slideshow and presentation mode), doesn’t play the soundtrack music or use the ken-burns effect in presentation mode.
Gwenview is nicer, but it shows the video playback controls while in slideshow mode.
I think those video playback controls shouldn’t be shown at all in slideshow mode, or there should be an option to not show them.
