I added the Assistant to my iPhone home screen for easy access, and the UI when running in a PWA isn’t great.

The background color for the web app seems to be white, leading to a bright white stripe at the top of the screen, as well as on the bottom when you attempt to scroll. The input box, mic, file, and send buttons are also awkwardly close to the bottom of the screen.
Add some padding on the bottom of the text box when the Assistant is running in a PWA, and change the background color (I assume) to match the color of the rest of the UI and avoid the white stripe. I’m not well versed in how exactly iOS PWAs work so if this is something out of Kagi’s control then I apologize!
