I'm brand new to Metabase.
So, on my very first exposure to the UI and the various aspects of it, I tried my best to form a conceptual understanding of the naming convention used in the UI and Documentation.
Alas, I do not know when, in my mind the very same thing, is either a Question or a Query, a Notebook Editor or a Query Builder, etc.
I get it that Metabase would be desirous of establishing itself as a unique tool, and tries to do so by using unique terms such as 'Question' rather than the industry standard, yet un-unique, 'Query'. But then please avoid confusion by using these terms interchangeably. If you're going to use 'Question' then also apply that to 'Question Builder' and not something such a 'Query Builder' or worse 'Notebook Editor' .
For a person having had many years of BI experience, I can conceptually form the links between the interchangeable nature of some of these terms, but pity on the new user without that experience and capacity....
