Jupyter notebook is already a good framework to write code like literature, and unfortunately, I don't think that we need a different tooling from SymPy to do that.
I just advice to make multiple cells, structure your notebooks well, and print the intermediate results of your computation often in your cell (use print or display) I don't think that it is easy for any computer algebra, or related tools to support 'step-back' functionality. I haven't seen that in other competitors, like Mathematica, too. The problem can be generalized to time-travel debugging (Time travel debugging - Wikipedia <https://en.wikipedia.org/wiki/Time_travel_debugging> ), and it is an area of research, if it matters how to do it correctly, or efficiently.
