Hi Chris,
yes indeed, all made with the package. And you can create your own templates by loading the <osdatadir>\LAVA\Control Templates directory with your own templates.
I will add a tutorial in this eventually, but it's a no brainer. Just look at the templates already in there and reproduce them to your needs.
I didn't include a batch processing utility, but the class is there for anybody to use it as such. The galleries of controls in those packages are batch processed.
