Just a thought – would be nice to be able to edit data types rather than/in addition to deleting/creating new fields entirely. Not only does that save the time on creating the new data type, but also with mapping all of the associated elements and workflows that were tied to the previous data type. I’ve found myself editing the field type quite frequently as the complexity of the application grows and am experimenting with different workarounds to solving problems.
+1 to this. At least to start off with going from text -> list of texts, number -> numbers etc.
