When I get plasma notifications that a message has arrived on my phone from kdeconnect, I'd like to be able to mark the message as read from the notification popup (just like I would be in the android notification popup).
This would be useful e.g. if I make a couple of ebanking transactions and get a TAN via SMS for each transaction. I read number in the notification popup, enter it in the browser and then the message is irrelevant, so I would not have to go through those obsolete messages on my phone anymore.
