I have filters configured on my gmail account to add labels to incoming messages based on sender, subject, etc. I'd like to configure the default gmail client to apply different notifications based on these labels. This post suggests setting up multiple gmail accounts, but that would quickly become unworkable, IMO. I've tried to change the notification settings while in a label view, and long-pressing on the label name in the label list screen, but neither leads to the desired result. I'm hoping there's something I've missed...
I just happened upon the GMail Label Notifier app. I think this will do exactly what you want.
This has recently become a feature in the native GMail app.
No, not in the native Gmail App.
