Hi,
I have on my todo list two things:
1) right mouse click or up/right arrow to go backward between slide (should be added in the next version)
2) “buttons objects” that can be added into the slide to create interactive presentations, menus or small game quizzes (later)
I will try to release the new version with point (1) end of next week, for the point (2) I will create a survey to know if users are interested in this functionality (as it requires some work).
Anyway thanks for your suggestions, they are welcome.
