But it looks like the Pluto developers are [quite open](https://github.com/fonsp/Pluto.jl/discussions/298) to ideas like marking cells for manual execution resp. introducing barriers, so there could be some interesting developments there If so, then they have changed their tune a bit (in a welcome shift!). It was their obstinance on this issue tha prompted me to go to the trouble of creating Neptune in the first place (at considerable time, trouble, and expense). If you want something which is not fancy but ‘just works’, Neptune is a good option. People have been trying to negotiate with the lead developer of Pluto for nearly a year now on this point, and he keeps talking about how difficult it would be … the truth is that it is not difficult at all… he just doesn’t want this kind of feature (hates the idea… he told me so himself before cutting communication). I think there is an avoidance of saying ‘no’ so as not to alienate followers, but (I predict) there will be more prevarication and little movement on this point. --- _[View the full topic](https://discourse.julialang.org/t/issues-encountered-teaching-classes-with-julia-for-the-first-time/56553)._
