Hi +Arun Kamath
, This isn't a feature now, but if you're using Chrome you can get this already kind of. On the top right (Mac) or on the bottom right taskbar (Windows) there should be a bell icon, from there you can mute all Chrome notifications. Not sure if there is an equivalent in Firefox and other browsers but might be worth a shot.
Snoozing is in our future plans though. It will take us a while though. Hope this helps in the meantime.
