When I play with the QML app it often crashes (mostly when changing modes). Then the LEDs do not work until I restart tohd.

If I understand correctly, if I want to support LeTOH in my pebbled, I need to copy verbatim the whole code driving the I2C to my project? There is no library/service I could just tell what to do?
