With iPadOS 15, Apple is adding extra little tidbits and fine-tuned features to improve on the user experience during multitasking. Again, some might argue it’s not enough, as iPadOS is still far from the multi-window interface that MacOS or Windows can get you, but Apple insists on keeping that tablet DNA weaved into the experience. Love it or hate it, it’s there.
But hey, at least now we have the Shelf — a new way to open and cycle through background windows for the same app. Note — this is not tab management, a-la Safari tabs, this is actual multiple instances of the same apps.
