Settings saved to
jalbum-settings.jap really matter. However when updating jAlbum the data get shuffled at random. So it's hard to tell what really changed between two versions.
I made it to a habit sorting the lines of
jalbum-settings.jap and saving to a new file as:
sort /home-HDD/karl/NeueBilder/jalbum-settings.jap > /home-HDD/karl/NeueBilder/jalbum-settings.jap.2015-01-20
Comparing the following backup versions directly
diff /home-HDD/karl/NeueBilder/jalbum-settings.jap /home/karl/NeueBilder/jalbum-settings.jap ~/Dokumente/jalbum43.txt
results in 172 lines of messy output (jalbum43.txt)
Comparing the sorted versions
karl@hofkirchen:~/NeueBilder> diff /home-HDD/karl/NeueBilder/jalbum-settings.jap.2015-01-20 /home/karl/NeueBilder/jalbum-settings.jap.2015-11-09
reveals that virtually nothing has changed between project versions since January (jalbum44.txt).
