Better notifications as a follower of a task
We used asana before and it was very useful for the person creating a task to be able to specify who the followers of that task should be - rather than people having to opt in to following that task. Those people then automatically received updates.
I run several busy large teams to would find it useful to receive updates on all tasks I follow as I did in asana. At present, teams doesn't seem to keep me up to date adequately on the tasks I follow. I don't get enough notifications to be able to keep tabs on what is going on.
