The current banner/alert provides the option to view the message only, please could you consider adding [Delete Msg] [Archive Msg] [Close/Dismiss] as additional selection options?
Note - this is a request for reusing the existing default functionality: I appreciate that allowing for Customised/User defined notification actions is a separate ball game completely!
If implemented, when combined with the request for enabling/disabling notifications per account, it would substantially cut down on interruptions/notification overload for users with multiple accounts and allow for improved workflow.
E.g.
Sales email slips through SPAM filter >> Quick Delete
Bumping this… even w/o the added actions, just a “Dismiss” box would be grand, as there’s no way to unblock things that are behind the notification and the wait can be truly frustrating.
