I've just released the Xtemplates Plugin in the Grails Plugins repository.
This Grails plugin increases the customization capabilities of the scaffolding templates. The default scaffolding templates are limited to generate list, create, edit and show views. With the xtemplates plugin you can generate any number of views. In the xtemplates generation process also a runtime loaded Helper class (which can be customized just like the templates) is binded so you can execute any code in the generation process.
I think both improvements would be a good candidate to be added to Grails core!
Just get started with installing the plugin:
grails install-plugin xtemplates
And then install the xtemplates:
The templates will be installed under \src\xtemplates\scaffolding
After changing the xtemplates you can use the following xgenerate commands:
