The Log pane is actually an implementation of com.solarmetric.log.LogFactory (see the Logging section for more details) that will log all messages and then echo the messages appropriately to your current logging configuration. We should see messages in the panels already from enhancing and adding mapping info to our system. Feel free to inspect these and adjust the logging to your needs. In addition, you may also inspect your own logging configuration to ensure that messages are being properly echoed to your own configuration.
Messages get logged here row by row sorted by date. The left column indicates the logging channel that is being written to. If you would like to see the complete text of a message, just double click on it to expand it into its own dialog.
