Make Arduino IDE Prettier

Arduino IDE is written in Java and it looks ugly as the default Look And Feel (GTKLookAndFeel) sucks on Ubuntu or similar systems.

So changing it to other swing LAF would make it a bit more pretty.

To do so, open /usr/bin/arduino as root. Then change

# Ugly
java "$@"


# Pretty
java -Dswing.defaultlaf=javax.swing.plaf.nimbus.NimbusLookAndFeel "$@"

After saving the file, run Arduino IDE. See the difference?
