Perfect, thank you very much. Unfortunately, the make_sparsity_pattern() method I was looking for is displayed after make_flux_sparsity_pattern() in my online docu., so I overlooked them, sorry for that.
That's a good starting point to add a method for each level and I need some flux sparsity for my DG variants, too. For any patches, I will address you on GitHub. Thanks a lot!
