Summary
Many powerful new capabilities have already shipped, which unlocked
new experiences on the web (Photoshop, VS Code)
The current focus is on fine-tuning the desktop experience
Some APIs have already made their way into other browsers (e.g., Web
Share)
Fugu process makes sure that capabilities are implemented in a secure,
privacy-preserving manner
Let’s make the web a more capable platform!
