I had succesfuly indtalled kite on K4NT using install script.
Thank you a lot, now i am able to run cr3 on my kindle !
Now about bugs:
1. When i firstly place to the kite folder file CoolReader3 with text
/mnt/us/cr3/goqt.sh cr3 start
and disconnected kindle from usb - i got cr3 autostarted immediately.
2. (The worstest bug i found) After closing cr3 (or any other application) i can see that anouther copy of this application is running! As i understend, kite in some way is lounching selected application twice! And that copy is not fully controlled keybord (When i am pressing 'menu' key, i can see that two menu are openning - one is from CR3 and another - original kindle menu).
Sorry for my bad English
