I develop IAB standard display ad units (once in a while, have done JS interactive ad units). I used to use Edge Animate (when Flash was kicked out by the world). When I moved to Adobe Animate CC, I didn't like it at all and found the element very restrictive and lacking in API support as well as accessibility.
I then found Hype. Yay!
I work from a Mac OSX El Capitan; I wish that Hype was cross-platform and would work on Ubuntu and/or Windows as well because I work from those platforms often enough as well.
Wonderful software folks! Thanks for it very, very much!
