I assumed i a will be able to develop (edit) and test my own scripts but that is not the case and it looks it is not a limitation of the free version; apparently it is a collection of pre-developed scripts and examples which are not even available for test on the free version , even less ; to develop, edit, debug nor test your own scripts. If the app has any use it is impossible to tell with the free version and i am not going to pay a penny to discover it….it is a loss of time….
