The "Activities" module has a feature which is similar to the "Ticket Peek" feature to view the contents on the side bar whilst also browsing the activity list. However we did realize that this peeking feature does only function on specific views such as "All Tasks", "All Activities" etc.

We tried to create custom views thinking that maybe the default views were missing this feature and we've found out that the "peeking" feature is disabled when we use the "Status" field as a criteria in the view.

Could you please check this issue.
