Why does Raccoon look different than in the screenshots?

Raccoon is written in Java and uses whatever theme is set by the Java runtime as the system theme. Unfortunately, this often defaults to "Metal". If you want Raccoon to look like a native app, open your filebrowser and search for a file called "swing.properties" (in your Java installation).

Linux users should append the following line:

swing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel

Windows users should append the following line:

swing.defaultlaf=com.sun.java.swing.plaf.windows.WindowsLookAndFeel

Afterwards restart Raccoon.
