Please add an option to have notification auto-expire (auto-read, auto-delete) after a certain amount of time, so they do not cause clutter

This is implemented in our API in the new "ttl" setting which is supported by our desktop app and iOS app version 4.0 rolling out now.

Limitations in iOS currently prevent notifications from expiring after a certain time unless another notification is received after it that can clear the first one, but messages in the app will delete according to the ttl setting.

A tandem idea would be to add an id field to the message.   When the client sees an incoming message of id=x, it could remove any existing messages of id=x.  Wouldn't have to try to figure out expire timing.   Thanks.

This is definitely a highly valuable feature for most of the users. Providing an expiration date to the notifications would save so many clicks.

I would be happy even if there was an option to push a notification delete through the API.

On the Apple side it seems to supported:

If you're on Android...you could use Buzzkill or Tasker. 

I would love this too, in the mean time, for android I use 'notification remover' to have the auto expire effect mimiced

I would love to have this feature. Please implement soon.

Seems like a basic thing to have and a strange omission.

I'm using Pushover to send notifications from Node-Red and have to say, I WOULD LOVE if this feature existed.
