Customizing Toolbars

I admit I am new to the whole realm of Java, building programs, etc. However, I’ve managed to follow the customization document and I understand the “concept” of the Sparkplug dev guide. However, I am unclear as to how to remove toolbar buttons from the program.

We do not need the phone button, and I would love to remove some preference options within Spark, but I am confused as to how that all works. Is there anyway or at least a sample jar file someone could point me to that would instruct me how to remove or add buttons to the chat window toolbar?

Thanks

Jen
