Your inputs now stay put while you build 
This is a big one. In the app builder, when the agent updates your app, the values you’ve already filled in on screen now carry over instead of disappearing.
Until now, every update reloaded the preview and wiped your inputs. So if you were partway through filling in a longer form to test something, you had to type it all over again. For anyone
iterating on an app, that was one of the most disruptive parts of the flow.
That friction is gone. You can now keep tweaking and testing continuously, without losing your place, which makes the whole build-and-test loop dramatically smoother.
Give it a try. We think you’ll feel the difference straight away.
Additionally, the agent can now move files you upload in the app builder chat to your app folder as well!
