Very important feature
I second this. Offline support would be tremendous for our use case. We have a team of doctors and therapists performing rehabilitation in patient's home. We use your forms to perform standardized assessments of their conditions. Unfortunately, often our patients live in the countryside where cellular connectivity is spotty at best. Being able to embed your forms into our web app while being able to save locally (e.g. to browser cache) when no connection is available would be a game changer for us.
another use case for this - where you want to give feedback to a user using show/hide without necessarily collecting any data from them.
This will help my clients navigate away from expensive alternatives that are necessary bolt-ons right now.
