definitely not visually consistent - although I have to give credit to Apple for the scale of ambition to roll it out across all of their operating systems at once (macOS, iOS, iPadOS etc.)
It makes it more glaring though that the iPad Pro really ought to be able do everything a Mac can, whereas Microsoft was there with Windows 8.
One of the most progressive features of iOS 26 is multi-window mode for the iPad but my first experience of it was playing Arknights where the main game mechanic is you drag one of your "operators" from the bottom edge of your playfield and instead of getting the desired effect the whole window broke loose. That game went from flawlessly smooth to a little janky.
Hopefully all of us complainers are wrong and this ends up being a smart strategic move by Apple but so far nothing is easier and many things are worse.
