Usually I copy a needed JAR into the projetc's lib folder.
Next step: add the Jar to the classpath.

This would be quite easy if you could just rightclick the Jar in the Files View and then have an option like "add to
classpath" which adds the jar to the projects classpath.

Currently you always have to use the Project properties or rightclick the lib folder and then search for the Jar again
(due to murphy's law, the last recently used folder which is opened by the filechooser is never the libs folder that you
want).
