This tutorial is amazing. Thanks for adding this info. Maybe some kind soul can help with one question. I can now add a new Tab, Group and standard buttons using the Xml method in the example, But I want to add a custom button that will display say a "contracts" category of the buiding blocks. For eg. I have added some content to the Builing Blocks gallery, with a new category I created called "contracts". So all that I now need is a button that will filter the Quick parts gallery and just show the content that falls into the "contracts" category. I hope this makes sense. Im no programmer and would be so greatful for any help the Guru's out there may have.
