I would love to be able to create a template, basically deciding the structure and styling, and also data source path of each element, but not the actual datasource.
Then when creating a klip, I could choose a base template, and just pick a datasource and change values of labels and so on as I see fit.
Then in the future if I change styling of that template, all klips implementing this template, change with it, including structure and data path stuff.
Only thing that isn't changed is hardcoded values, these are always overriden from the actual klip implementing the template.
