Top-bottom split screen feature on iPad
I'm currently using an iPad 9th generation for my study needs. Often, I find myself needing to keep both a PDF reader app and a note-taking app open simultaneously. As my iPad's screen size is limited to 10.2 inches, the existing side-by-side split view feature in landscape mode isn't effective for this purpose.
It would be highly beneficial if the option to split the view from top-bottom in portrait mode were available. Some Android tablets already offer this feature, and it surprises me that it's not yet available on the iPad.
Is there any effective workaround to achieve this feature?
