Right now, this is the workflow for managing notifications:
1) Open notifications panel
2) Find the task you want to respond to
3) Click on task
4) Respond to task
5) Close Task (which for some reason automatically closes the notification panel)
6) Re-open the notification panel
7) Desperately search for the task you were interacting with
8) Dismiss the notification
Honestly, it would be even better if responding/taking action on the task automatically dismissed the notification, but I'll settle for just not losing my place in the notification panel every single time I respond to a notification.
Notifications at this point in time are a real pain to deal with, especially when you have 40+ notifications
