The Inbox can be a little overwhelming sometimes because of all the tasks that are being followed. Not all of them are top priority - some are just to keep an eye on, while some need active engagement from me or other team members.
It would be really, really convenient to have a filter by activity type - as the main example, being able to show only comments mentioning me (and/or only comments in tasks that I am following) would make communication in Asana much more streamlined. As it is, my Inbox is flooded with new tasks, files being uploaded, completed tasks, etc. And it is sometimes hard to decipher what I need to respond to and what is just noise.
Another use case would be for Completed Tasks only, to be able to see what you’re following that has been completed recently.
