Inbox Sorting By Collaborator/User

I’m grateful for the sorting updates to the inbox. However, I still find myself wading through a see of “notification” looking for “comments” about a project.

It would be ideal if you could

  1. filter or search the inbox for a certain user. (ie, show me inbox notifications from a certain user)
  2. filter inbox based on notification type (ie, task updates, comments, etc).
