I'd love to help > I am not sure how feasible it would be to implement the default interpreter per notebook rather than per interpreter setting. Implementing it per setting is straightforward, as we just need to bring the interpreter to the front of the group associated with that setting. From my understanding, it seems that making it per note would take significant changes in various parts of the codebase. Implementation side, agree, per setting is more straightforward. However, in ux side, i still think it's confusing to have "default interpreter group" per notebook, "default interpreter in group" per setting. It's not going to be easy to make user understand this different strategy for two similar actions.
