A new, updated Visual Editor is now available. Create beautiful layouts visually while the editor automatically generates the corresponding code, making web development more accessible and efficient. Check it out [here](/replitai/visual-editor) to learn more.

### Extended app preview time

Your app previews now stay active for 10 minutes after closing your workspace (up from just 20 seconds). This provides a much smoother experience when multitasking or sharing your work, especially on mobile devices where you might switch between apps while testing your project.

## Teams and Enterprise

### Team member app transfers

Organization members can now transfer their apps to other members of their org. This feature solves key collaboration challenges, letting teams redistribute ownership of apps as projects evolve and team responsibilities change.
