Thanks for the replies.
Michael, hopefully they will implement something similar to what you suggest 
Actech, thanks. I have just realized that it was you the one that suggested to use the timer to call global functions. When I saw it two days ago, I used it to organize some of my code and it was very helpful, thanks a lot!!! regarding to the topic, could you please confirm that I understood it correctly?
Right now, I have the attached image in which everything is in the same “screen”: when this screen opens (PreguntasMenu) it will create different buttons based on which button the user pressed in the Menu screen (previous screen): if the user clicked on Lectures button (VengoDe=2) it creates buttons for each Lesson (Lesson 1, Lesson 2, …), if the users clicked on the Questions button (VengoDe=4) then it will create the buttons for the questions for each Lecture, and so on…
If I understood correctly, your suggestion is that I put the functions in my “loading screen”, make them global using the timer, and then call them in this screen (this step is already done). I don’t understand why should it be faster… wouldn’t it take the same time to read the function despite its location? or you mean that the fact that all this functions are in one screen makes it taking longer to load the screen?
Thanks in advance
