Another quick release to add a little feature which enables or disables the popup "tracker window" that appears when a new song begins. Nothing magical or fancy here - it's driven by an application configuration setting rather than the user interface. But it's easy to do!
Navigate to the iTuner Program Files location which should be "C:\Program Files\River Software\iTuner" and crack open the iTuner.exe.config file using a text editor. Look for the TrackerEnabled setting and change its value from True to False. Restart iTuner and now the tracker window is disabled. Easy as that.
Note, if you're on Windows 8, you may need to enable write-access to the config file first and then run your text editor as "administrator".
