is it possible to extend the project tree?

Hi all!

This subject has been touched upon but I couldn't find any up to date answer; I would like to add a "Web Services" node to the project tree (just like the "Libraries" node) containing other nodes related to my soapUI plugin.. is this possible? Is there some kind of tree-model available that I can extend? Are there any example plugins I can look at?

Thanks for any reply!

regards,
