I'd love to see custom script functionality built into the Chrome/PC extensions that can be programmed to open certain web pages when you click on a Join notification from a particular app. For instance, if SlickDeals android app sent a notification to Chrome, and I click on that notification on my PC, I'd like it to open up that slickdeal in a Chrome tab on my desktop vs sending the action back to my phone and it opening up Slickdeals app to that deal. That's just one app example. The custom scripts would vary based on the information provided in the notification and what app it came from. NextDoor or Facebook are other apps that come to mind that could use that feature.
