We use the yes/no field frequently on manual Flows to toggle different actions and branching logic. For example, if Toggle Batch is selected, run all award letters for the current year. If it's not selected, only run one letter with the values provided from a text box.
This works great, but the branching can often times get confusing when we have several of these on one Flow. It would be helpful if the description field on the Yes/No buttons was somehow exposed (perhaps on hover) when a user manually runs the Flow.
