The latest Gmail app update (26 MAR 2013) introduced a feature for devices running Android 4.1 (Jellybean) and higher wherein a user could directly archive / reply to an email from within the notification pull down.
The "What's New" section on the Play Store however also lists the ability to delete an email.
Android 4.1 (Jelly Bean) and up: • Reply, archive or delete from notifications - no need to open the app
I'm running CyanogenMod 10.1 (Android 4.2.2) on my Samsung S2 i9100 and the options for Archive and Reply show up when I pull down the individual email notification but nothing for Delete shows up, even while in Landscape mode. Any ideas on how this can be implemented or a setting that I've missed to enable this functionality?
