1. What is the general goal of the feature?
When prompts are grouped in ODK-X Survey using "begin screen" and "end screen" in the XLSX converter, show an optional screen header. This could be taken from another column on the "begin screen" line in the XLSX file.
2. What are some example use cases for this feature?
If the prompts that are grouped all relate to a subsection of the overall survey, a label at the top may allow the individual prompts to be shorter and more precise. For example: I am collecting a meter number and reading for a meter being removed, as well as for one being installed. I could label at the top of each screen which meter the inputs on that screen is for.
3. What can you contribute to making this feature a reality?
I don't know any of the languages used for ODK-X, but would be happy to help with testing.
