As an idea - it would help in case of Performance issues when we could see the number of currently active users in Proactive Pack - the username would help a lot in combination what he's actually doing (e.g. running the query <query.name>) and uses how much CPU/Memory.
This is an interesting evolution. We cannot include it in our next release (3.3) but will analyze feasibility for the following release.
Thank you for the idea.
By the way 3.3 will include a user login report - providing statistics on the number of named users connections over time.
