Sometimes I just get a bit disheartened by the application.
Today I did the first customization after the latest name change and I get to pick field type "choice" or "choices". Not much information so I turn to Google with "dynamics 365 choice choices".
That search didn't go well, or, the search did just fine but the results weren't really helping me. SO I modify it to "dynamics 365 column type choise choises" and the first hit is this page https://docs.microsoft.com/en-us/dynamics365/customerengagement/on-premises/customize/types-of-fields
which tells me that I can use optionset or multiselect optionset.
I suppose "choices" is multiselect optionset, which somehow sounds a bit more intuitive than "choices".
Call me old.
