Every screen in your app is a page, and they’re all managed from one place – the Pages bar running along the left edge of the App Editor.
Steps
1. Open the Pages bar
It’s docked to the left edge of the editor and lists every page in your app.
2. Add a new page
Click Add Page to create a fresh, blank screen.
3. Rename a page
Select a page and rename it to whatever makes it easy to identify later.
4. Duplicate a page
Duplicating copies a page’s entire layout and content – a fast way to start a new page that’s similar to one you already have, rather than rebuilding from scratch.
5. Delete a page
Deleting asks for confirmation first, since it removes the page’s layout permanently.
6. Collapse the Pages bar
If you want more canvas space while you work, collapse the Pages bar – it doesn’t affect anything, it just gets out of the way.
