What´s fine?
- Clear structure in designs.

What´s missing?
- I´m in Germany and I cannot use a button in f.ex. a banner with an English text. Found no possibility to change and got no reaction on my request.

- I copied the code for Apple and followed the instructions. It doesn´t work. Same request, no reaction.

- Designs offer too less possibilities to change positions of elements.

This is the first experience, maybe it will get nicer in the next weeks. For the moment I cannot use it and really was searching for exact such a tool.
