Relevant to delete / undo they talk of the preference for an undo (eg ^Z at any time) to "Are you sure?". No mention of delaying action or availability of undo. Then preference for consistency of action - within app and generally, not deviating from common expectations (eg that a trash can allows restore), and recommendations for visual feedback when latency and delay is involved. None of which fits the original temporary delay/undo.
In both of those links I posted, it clearly states well-designed systems have undo.
Well, and it is also much easier to quickly locate and hit an Undo-button on a small touch screen than it is with a mouse on a giant screen.
But yeah, I definitely also see a lot more confirm-dialogs still.
Seems to be a classic case of such a UI pattern being great and hyper modern and marketable in 99% of cases. But if in 1% of cases, the user accidentally deletes a file that they didn't want to delete, then you lose that user in that exact moment.
That is, if you are not a preinstalled app. If instead you are Google, then users are generally not aware of alternatives and cannot switch away from your app, if this happens to them. They just live with your UI eating their files.
Not to mention that it was quite clearly their fault for not finding the Undo-button quick enough. Which is also generally an opinion that users manage to hold, who have not yet progressed to looking at alternatives of programs and comparing different UIs for their merits.
Perfect example of a UX pattern that's simply asking for trouble, or being clever rather than helpful. :)
You can undo if you notice quickly enough, if your dog, child, doorbell or 1,001 other things didn't distract you at the wrong moment and if you didn't get an incoming call in the temporary undo window. No, we won't tell you how long you can undo for, even though times can vary. Don't be old (or even middle-aged needing reading glasses), or slow.
Seems very much against long known recommendations from Nielsen et al for consistency of expectation etc.
A quick skim through search seems to indicate it came with Material Design. I suspect had it generally caught on it my switch to iOS would have come even sooner. :D
> 99.9% of people know what they're doing
You have very different users than those of anything I've ever written then. :)
