### 3/5 — Missing pieces in Example

*2018-09-25, version 1.0*

The full example is not visible because of a back button. This cuts off the method signature. If you REALLY want to see the full example you could export it. You get 5 freebies, then you get to pay after that.
Please fix this problem.

**Developer response:** Thank you for pointing to this issue. Fixed in version 2.0.
