Currently, on the activity timeline (e.g. for a deal record), we are not able to filter the tasks based on completion (e.g. upcoming tasks, completed tasks). The tasks will then fill up the entire timeline and it makes it difficult for the user to actually view what are the upcoming tasks. However, if the user filters out all tasks in the timeline, then the user is not able to actually view the upcoming tasks.
It will be great to have an option to filter tasks based on completion status 🙂
