In Mathematica versions prior to 11.2 or 11.3 (not sure at the moment) it was possible to select the default format type of new output cells via
Preferences -> Evaluation. In particular, it was also possible to change it from
TraditionalForm, which I personally like very much.
From the point of view of a package developer,
TraditionalForm typesetting allows to make the output more visually appealing and close to what people see in books and papers. And it is also quite fun to develop
TraditionalForm typesetting rules. I understand that sometimes it might be confusing to new users, but the
StandardForm is often just too inconvenient to read, so I actually only use it to copy and paste expressions.
However, in more recent Mathematica versions this option was removed from the preferences and is now "hidden" in the Option Inspector. A new user not aware of the existence of
TraditionalForm would now always see only the
Does someone know why this happened? Were there perhaps some recent statements from WRI regarding the future of
TraditionalForm? I truly hope that it is not going to become deprecated or something like that.
