The method in https://github.com/hwhw/kindlepdfviewer/issues/653
just provided a proof-of-concept way to launch external reader directly from home screen. As @eureka mentioned in the above post there probably is better way to associate additional file types with KPV. I hope we can find the best when we release the brand new version of KPV. For now if you really want to try KPVBooklet you can firstly backup the file /var/local/appreg.db and copy mimes.sql into /var/local and run 'sqlite3 appreg.db < mimes.sql'. Then you can restart framework to activate it.
