Over the past few years, we have found that small-scale "substructures" -- emission deviations on ~few-AU scales -- are prevalent in protoplanetary disks. We expect that these play fundamental roles in the evolution of disk material, and may even trace ongoing planet formation. Prof. Andrews reviews what we've learned so far, primarily from observations with ALMA, discuss the current limitations, and look forward to new opportunities for continued progress in quantifying and explaining the origins of these substructures.
