Add a slider response type
One feature requested by others at my institution before they would consider moving to Microsoft Forms is to have a question type where a slider can be used for the response, like Qualtrics offers: https://www.qualtrics.com/support/survey-platform/survey-module/editing-questions/question-types-guide/standard-content/slider/
This is also important for my team; in fact it is likely to be important for many health-related research studies, particularly when participant literacy is low. The concept that a quantity increases as one moves a slider (by touch and drag) is more intuitive than numbers are.
