Hi everybody,
long time no blogging. Time to fix this bug. So...without any long prologues - (hold your breath now) - it's working! (Say WOW™). But how well does it work you ask? Pretty good! Ok ok, let's get some overview.
You open some image in digiKam's image editor, you add some filters, do some transformations, use some color-altering-stuff untill you're satisfied with your creativity. Then you simply close the editor, autosaving kicks in, and bam, you have new version of your original image, which stayed completely untouched.
