Yes. I have already add the mentioned fix into KPVBooklet otherwise additional file types cannot show up in the home screen for Kindle touch. And I enumerate all ContentCatalog's declared methods and check their parameter types to find out the obfuscated query method in runtime. This enumeration approach works fine on all firmware above 5.1.2 in spite of the obfuscation. I hope it will also work on earlier firmware of version 5 but I can't test it.
