title: Looking for a Split View Debug Viewer to visualize Logs of Asynchronous Systems
body: <p>To visualize asynchronous log output, I am looking for a log4j/net compatible debug viewer with a split view that shows log lines selectively on the left or right. The selection should be based on a set of loggers or string patterns.</p>
  
  <p>Preferably, lines on the opposite sides should be empty and the views' scrolling synchronized.</p>
  
  <p>Have you seen something similar, or even know another, better way to visualize log output of asynchronous systems?</p>
