I have a couple of questions, as I never used KOReader before:
- does it read both EPUB and KEPUB files?
- does it have its own hyphenation dictionary for Polish? If not, does it read soft hyphens for EBUBs and KEPUBs or should I install such a dictionary on a device?
- does it disable reading stats for KEPUBs, i.e. are these tracked only in Nickel?
