Why not supporting chm format?? – KyBook 3 Ebook Reader Review

One of the best ebook reader after checking many apps. It will be perfect if you support chm format too, like the previous version. Why don't you give your previous version owner some discount? Should we buy the next version after paying for this version and even more for a subscription for syncing our data over the icloud?
