As Ressy said, I usually have other programs/tabs open while running Feralheart, such as lioden, tumblr, Sai, or the forums. I'll multi-tab with a few of those things, but otherwise, I'll watch the chat whisk by. It's interesting to see a lot of the conversations that go on from map to map.
If Feralheart is quiet, with not many people on, I like to go into private maps and take screenies.
