Yes please! Can be more or less as the new Comments column. But an eye-icon with the amount of watchers. With onclick a popup just like the assignee column to quickly add or remove watchers.
Even if it's just the number of watchers for each task, this would help a ton. Hopefully this is added soon!
From support ticket: I want to show watchers, not add them. Just as I show assignee, I want to show watchers as a column in the list view.
