Apologies for the crazed pull requests--- I can see how the outputs can be confusing and then rushed to git rid of the output causing my self all sorts of problems and taking longer than if I just read the documentation so I did it right the 1st time (sigh). Anyway the tutorial build is clean now -https://mesa-geo--231.org.readthedocs.build/en/231/tutorials/intro_tutorial.html#part-3-add-interface; I would say once this is merged 0.8 is ready to go; Thanks for the label @wang-boyu
