Allow selection of which connection is monitored.

My computer has multiple adapters/connections and the only info seen in this program is my ethernet connection, which I rarely use. I use my wireless adapter, but cannot monitor it with this program. It would be nice to maybe either select which one gets to be monitored, or monitor all adapters/connections and then let the user be able to switch between them, looking at the data for each of the connections (without losing the data for that session)
