Event log would be amazing, with information like "client A connect to AP 1 at 4:45am", "client B roamed from AP 1 to AP 2 at 5:32am", "client C disconnected from AP 3 at 4:54am" - it would help me narrow down where to dive deeper for troubleshooting client connectivity issues.
Ideally this would be accessible locally, and if on AP or client detail page, only for that specific device/client.
I don't think i need this data retained for too long - 80% of the cases troubleshooted would be in last 24h. 3 day retention would probably cover 99%.
