Thanks to @busy-branch-28834’s visual browsing -- OpenHands can actually test some simple UI by serving the website, clicking the button in the browser and looking at screenshots now 🙂 Prompt is just:

I want to create a Hello World app in Javascript that:
* Displays Hello World in the middle.
* Has a button that when clicked, changes the greeting with a bouncing animation to fun versions of Hello.
* Has a counter for how many times the button has been clicked.
* Has another button that changes the app's background color.

Eager-to-work sonnet 3.7 will test stuff for you without you asking 😅

Amazing
