Thanks @eruditionastic - that's great work.
Even better that it was a work out of love!
I'll see how I can include them in the main release.
About future kindles, I had a PW4 to setup and was ready to jailbreak it, but embarrassingly accidentally updated over wifi... so the chance of getting to make KindleLazy work on PW4 was delayed until I can try again
Once I remember/re-learn how to set up the necessary development tools in order to compile kindle stuff, I'll make a few little updates.
Thanks
