I´ve looked in the forums, and the idea is new. It would be great if there would be an option to make it possible to give tooltips when writing a formular yourself not only in the "basis-language of the installation", but also in e.g. english (as Lingua Franca). The reasoning: in Excel or Tableau I know many a command in only one language - and have to undergo a timeconsuming process of A) thinking AND B) looking it up in the language you have to use at that project.
Even Tableau does not offer this - and you have to create a lot of calculated fields. Alteryx could gain in UI-friendliness...
