Unfortunately, Retool Forms isn't something we're prioritizing right now, so your best bet is using the form component in the app building canvas instead. Assist has also recently had some really solid improvements specifically around building form components, so getting something up and running is faster than ever. Here's the announcement.
For your use case specifically, I would recommend building a single Retool app with Assist: one app, one consistent UI for all your forms and responses. You would describe what you want to Assist (e.g. "a tabbed app where each tab is a form, with a shared response viewer"), and it scaffolds everything for you. Adding a new form down the line is just adding a new tab, no new app to build or maintain. More flexible, more control, and built to scale with you. What do you think? Let me know!
