Good to know, I'll always prefer working with cell delimiters like in Spyder over working with Jupyter Notebooks. I've also tried out PyCharm Professional, but the experience with cells and iPython was just worse for me than in Spyder - so I'm only using PyCharm for refactoring right now. I think the main problem was that errors/results from cmdstanpy would simply cause PyCharm to crash/hang instead of getting handled properly like in Spyder.
