I am eagerly awaiting an important-to-me email notification. I currently have a filter set in Gmail to trap this message and flag it as important, never send it to spam, keep it in the inbox, and label it.
Once that email arrives is there anything I can do to make Gmail even more active or obnoxious to advise me of its arrival?
Can I generate a Hangouts message to myself when it shows up?
What is the current state of desktop notifications and can those notifications be bound to a specific filter?
