When an Issue needs special attention, set its escalation property in Issue Details. A user can filter on this property to view them separately. When special attention is not required, clear this property. When an Issue is escalated, a Red Finger Pointer is displayed in the Title's Bar in the Issue Details section and also in the Issue List section.
An Issue can be escalated by clicking the Finger Pointer icon available to the right most corner of the Title Bar. Upon escalating an Issue, the pointer turns to red and is displayed in the Issue List section.
