Finally I was able to prepare new official version. It is so many changes that it is hard to mention it all. Main changes:
– reworked User Interface – panels can be switch on/off
– reworked communication with camera
– added and fixed some functionalities
– added function for activating/deactivating debug mode in camera
It was tested by few people with different equipment and I received very good opinions, especially about stability. Some long term test was done on K20, K5 and K7 with more than 1000 photos in series for each – purpose was checking battery power consumption during tethering.
