Your comments

I am interested too.

How does this happens exactly?

I don't have a finished app to publish yet, I only see that if I push the "Publish" button, it redirects me to the interact player website in order to make the payment.

It would be good to have a sequence of screenshot highlighting the different path to follow in order to publish the app under our own developer account.

Thanks
I have just downloaded the Builder, and it looks interesting, as it seems powerful and quite easy to learn and use. The lack of such a basic and fundamental feature in animation such as the easing effect, though, makes it less usable to produce professional looking animated books and therefore less appealing.

It is a real pity, I hope this feature will soon be integrated in the Builder. (this option already exists in the software made by one of your competitors, the PlayTales Builder)

Thank you again for your time.
Thanks for taking the time to answer my question Alin.

I would like to add a more natural movement to objects and characters.
In Flash this is easily accomplished with the easing function.

Here you can see some easing examples that show what I would like:
