But how can I get the application itself? Or is accessing attributes  
of the application directly in the templates considered a bad idea?

My suggestion wasn't as much about viewlets as about making the  
application object available in templates. It's currently quite tricky  
to get the application anywhere, and I'm still not sure what's  
considered the correct way to do it, whether by utility lookup or  
traversing __parent__ until we find the Application.

Thanks,
