What is the general goal of the feature?
The xform designer can select a specific app to be used to take a picture.
What are some example use cases for this feature?
In my case, the xform designer needs to notify the field data collector when a picture is blurry, especially for pictures of a document. We have a specific camera app which detects too much blurriness or too dark pictures.
What can you contribute to making this feature a reality?
We can provide an implementation of this Widget.
