[IMPROVEMENT] Expand sub-agent working activities

I have implemented a sub-agent. The orchastrator has called it correctly. But I would like to expand the visualization of their activities.
Some times pops up the "ctrl + r to expand", sometimes not. But anyway, the visualization is not in realtime (third image) like the Main agent
