Filtering:
1. Filter log entries on the message, a certain thread or the level with a easy-to-use interface . This animated gif shows the filtering in action. First, the message is filtered by typing op, then the main thread is selected from the list.
2. Colorize log entries based on the message, the thread or the level or a combination
3. Ability to define color filter groups
4. Set the timezone of the logfile (useful if you have received a log file from a different timezone)
5. Retains row selection and keeps that row in view when changing your filtering options
6. Show a tree of all loggers. You can also hide/show loggers through a popup menu.
