One thing I find challenging when teaching Pharo to new students -- especially those accustomed to IDEs with files, which is pretty much all of them ;) -- is that there are sometimes menus (depending on the Pharo version) to add a new package, new class, new protocol, but not a new method, etc.
For onboarding new users, I think it's important that these things be intuitive and consistent, especially since updating tutorials takes time. They are super important because inconsistencies become barriers to onboarding new people. My point here is not that a menu option necessarily exists, but that we have a consistent way to explain how to create things even when Pharo changes. Apple used to have 10 commandments for keyboard shortcuts, and I think a similar idea could apply to having consistency in these elements of Pharo.
