Feature description

I think the title is clear enough.

Why do you want this feature?

It would help avoiding accidental deletions and would increase the coherence with what happens when deleting a message from the thread.

Additional information

There have been several requests about customizing the notification menu (also) to avoid unintentional deletions (e.g. #93, #358, #490). I think this feature would be a step forward towards those requests (but customization would still be a great additional feature).

Come to think of it, a "Undo" button similar to Gmail would fit better here.

I confess that I do not like it too much. Never used it, and when I wanted it had already disappeared. Would it be “permanent”, I mean associated with a “close” button? Would it replace the confirmation when deleting in a conversation (so, not from the widget)? I think it would be worth to have coherence in the process when deleting from everywhere. Just some early morning thoughts. 😴

I do not like those in-app Undo snackbars either, but from the notification, it feels awkward (misleading even?) to show a confirmation dialog over the user's current app. A notification action button seems like the least surprising way to do it.

Would it be “permanent”, I mean associated with a “close” button?

No, the Undo notification will disappear automatically after a few seconds.

Would it replace the confirmation when deleting in a conversation (so, not from the widget)?

No, in-app deletions would work as they do now.
