I wasn't aware of this, despite having used enough Android in the past. Shows you how many implement it, I suppose :)

Or how well you advertise it. Apple heavily promotes every feature tiny or large, while usually most of the cool Android ones get ignored even by the tech writers who are supposed to know about Android, let alone regular people or press.

Or that lots of Android apps are shoddy iPhone ports by developers who approach it as a second class citizen, and so are unaware of what it can do.

And then they complain that Android users don't buy their apps...

For example with emails you see this – get a new email, in the notification you can click on "delete" (as I get far too many unnecessary mails) or, if accidentally deleted, undo it again. Or click on Reply and directly write a reply.

This works with AOSP Email and Gmail (maybe others as well).
