ODK 2.0 tool :household/household_member


I am working with ODK 2.0 tool and I rely on household/household_members sample. After searching in odk web site and gitub, I would like to have a few details for this point please.

I want to change the appearance of attached view. I want to change " NAME" by “ID” or " Hour". Where can I find the folder which establish the view ?

Moreover, in this relation super-table/sub-table, super-table can share a variable with the sub-table. Is it possible that sub-table return the variable modified at super-table ?

In the queries sheet, in the auxillaryHash field, I would like to have more details on different functions used. Where can I find the function’s library ?

Thanks for all answer.
