A field that is automatically updated with who has browsed a node within a specific timeframe - for example the last hour.
If I'm looking at a problematic node it would be good to see if another engineer is looking at the node as well.
Especially in our environment where there is a large geographic separation.
The field would be displayed beside a node in the "All nodes" resource, and be available as an additional field to add to Web-based reports
I've done a screenshot of what I'm thinking of.
