Past/Completed Tasks and Comments Deletion
Completed tasks stay in the activity chain on any given file. This along with a long list of comments stalls the activity window while it tries to cache all of the past and current comments and tasks. Currently we have our users deleting old comments but we can't delete completed tasks. We need a way to delete old history in the activity window for any given file or your system needs to cache the activity so it appears instantly, sometimes it takes more than five minutes to be able to make new comments/tasks around a file.
The comment to a task may contain information that you don't want to share, even if you want to share the fact that a task was assigned.
Our team has come across this issue too. One of our staff accidentally added an approval task to a file and it stayed there when it was approved. I had to download the file, delete it and re-upload a fresh copy to remove the task.
