Hi Oleg and thanks for your feedback.

Vincent, I hope your tool will be a success, as it is really well crafted. But I really do not believe in your business case: it is a nice toy and those putting too much effort in effects rather than content will surely play with it for a while. However, the best presentations are indeed simple in design yet powerful in their message and presenter personality. I doubt you will get those people paying, but I will be happy for you if you can.
