Thank you for creating the launcher. I've successfully installed it on my PW2 (FW 5.11.2) and it worked perfectly.
Just a small suggestion, maybe you could include a simple installation instructions in the Readme.txt. It has been a long time since I installed any packages on my Kindle, and I almost forgotten how to do it

. For those who also forget, the 2 install .bin should be placed in the mrpackages folder in the root of your Kindle.
