Quite wonderful application, but I ran across a user case not covered well over the weekend;

If the network connection is unreliable during the "send" phase, the application seems to freeze, unable to continue or stop the sample sending to server.

This is a bit awkward, as there seems to be no way to make it stop and send the same sample again when network is available. Also, even when I leave the application open in the sending phase it will never recover, even when I get back full connectivity.

I feel it would be nice to use this so that when you hear something that you want to search for but there is no network, you could save the sample for later retry. That could be implemented so that when sending fails, user is notified and sample is stored to disk waiting for resending. There should be possibility of continuing to capture new samples during network outage.
