Basically, complex surveys can have a bunch of hidden fields. These fields are important to the forms proper function, but testing them can be time-consuming and convoluted.
Usually, testing involved making fields visible (e.g., converting a "calculate" to a "text" and adding a "label", then saving testing, and finally reverting those changes). Additionally, some bugs can cause things to break in production (e.g., I've had external selects stop working before, but had to inspect the server to find this out).
Basically, I am looking for a button in Connect/Field App that opens a second panel which displays the current results of all fields (with a search bar to isolate specific fields). That way we can build a survey in it's final form, but also thoroughly examine the results of hidden fields both in testing and production. Honestly, even if it only showed fields with the "hidden" appearance or "calculate" type, that would be totally fine.
