I sometimes find that scenarios lack documentation, particularly when it comes to documenting individual steps within a scenario.
Additionally, I am disappointed that (IMO) the new versions of Dataiku have resulted in a less user-friendly documentation experience. The 'summary' tab has disappeared, and the scenario description is now located in the right panel (as shown in the following screenshots).
dataiku v9
dataiku v11
In my opinion, restoring the previous configuration would make the scenario description more visible, which I believe is preferable.
