Hi @Darryl 
If I got you right, you’re talking about implementation of the form functionality to the Calculator app.
At first sight, implementation of this functionality might seem easy, but this is a very complex feature, and, unfortunately, we keep encountering bugs during testing.
Our devs are doing their best to deliver this feature as soon as possible and, hopefully, we’ll be able to change the status of requests to “Released” in the near future.
All the update will be posted in these threads:
