Many of the reusable django apps don't include default templates inside. James Bennett says in his presentation Reusable Apps that providing truly portable default templates is very hard. He adds that most of the bug reports in the first release of his registration
app were related to default templates.
This is a valid point. But without any default templates, it is very difficult to understand how an app can be reused, because the programmer can't see the reusable app in action.
What do you suggest to overcome this problem?
