Not a single marketing shot/screenshot of somebody using Final Cut Pro or Logic in Stage Manager mode… 
@stroughtonsmith deffo UIRequiresFullScreen apps
@bzamayo I’d love to use a slide over of Final Cut Pro X lol
@stroughtonsmith All pro app marketing shots are in full screen. Aside from Xcode.
@stroughtonsmith @viticci My take is that Stage Manager should have always been limited to external displays on iPadOS. Any changes to Stage Manager announced at WWDC will be telling, and lack of changes would be even more telling.
@stroughtonsmith On the Mac those apps are mostly full screen too
