High CPU usage

Andrea, thanks for flagging this. The latest update (1.0.51) significantly reduces how much CPU Charm uses while you type in a browser. To respect your per-site settings, Charm checks which website you're on, and that check is now far lighter and cached, so it no longer keeps the browser working hard in the background. If you noticed your browser feeling heavier with Charm running, this update resolves that. Really appreciate the report.
