I was using JUL and loggui (http://www.informatrix.ch/loggui/index.html) to edit logger's level at runtime and look at application logs in our Swing applications; it is very useful when applications are deployed using Java Web Start (jnlp environment)

I switched to SLF4J 1.6.4 / LOGBACK 1.0 last week.

As I wanted LogGui features for LogBack, I made it = LogbackGui (1 single and standalone java class):
This class provides two major functionnalities:

• application log viewer
• one simple log GUI : Logger hierarchy browser / Level editor and displays current logs

This class is dedicated to Slf4j @see http://www.slf4j.org/ (MIT License) using Logback @see http://logback.qos.ch/ (EPL v1.0 / LGPL 2.1).
