Nice, though I would move the "Add recipient" and "Send" buttons out of the scrollarea, so that they are always visible, just like on the address book page.  

The connection status indicator could display some additional information in the tooltip that there are connection problems if there are 8 or less connections/all connections are outgoing, kinda like a lot of BitTorrent clients already do:

Maybe that would cause more users behind NAT/firewalls to forward port 8333 and/or use upnp.
Also the fourth bar should be green and not yellow
