We need more domain specific tools like this, of course with professional end result. Most of the current graphical tools are big and slow with thousands of features, that you don't need to make simple animation is way to much complicated (and they don't work on any platform). I will try it!
It's hard to stick to core features during development and not wander off into the weeds. Most massive tools try to do so much. Some of them really do a lot and they do it well, but then they end up expensive and difficult to use.
