After 'refreshing' kindlet-jailbreak and localization files, all was well and functional again, even all my font, margin, etc. settings were restored.
Now trying the new justification setting in hyphenation patch.
Changing to 'ragged justification' in my mobi-files (floating text) does not make a difference, the text stays 'fully-justified'. After changing the option I did a 'System/Restart Framework' in JBPatch, also a 'Menu/System/Restart' effects nothing.
The ragged is a fallback in desperate need. It only shows a left-aligned line when it absolutely has to. Similar to what the Kindle does by default. If a line would have too much whitespace it will display as left aligned. JBPatch does such a good job, that it rarely happens. You can force it by e.g. increase minimum first and last syllables to a big number like 5 or so. And then try it on a large font size, and you will see some lines in justified text that don't reach the right edge.
