beaTunes 4 has a fairly modular architecture. Most of it is actually implemented as a plugin. This makes it relatively easy to add custom components.
Starting with beaTunes 3 you have two options to write a plugin:
- A Java plugin
- A script beaTlet in Groovy, Jython or JRuby
Java plugins let you write complicated logic, typically consisting of more than just a simple class. You can also bundle JARs, declare a plugin descriptor along with icons etc. Additionally, Java plugins can be distributed through the central plugin repository, if approved by tagtraum industries.
In other words: If you want to start a bigger project, Java is the route to go.

beaTlets have been introduced in beaTunes 3. They are Java plugin's little brothers. Whatever you can script together in a simple class, is a good candidate for a beaTlet.
