Slide Over is genuinely convenient. Certain apps work better than others inside the Slide Over deck, and when they’re optimized, their convenience is unmatched. I keep a calculator app in Slide Over at all times, I keep an iteration of all messaging apps in Slide Over, and I like to keep an iteration of the Files app available at all times. These kinds of “in-and-out” apps are exceptional for Slide Over.
At least one person really likes multitasking on iPadOS. The thing about the Slide over feature is that it requires setting it up. It doesn’t happen “just like that”. I rarely find the right app to use in the Slide over view… I need to “bring it in” and this is where the experience falls apart. This is where I want to see Apple improve things.
