The present disclosure relates to systems, methods, and non-transitory computer-readable media for using modularized digital editing action blocks in a graphical user interface to generate and apply a variety of advanced modifications to a digital image. The disclosed systems can categorize the digital editing action blocks into digital editing action categories from which a user can select a digital editing action block and insert into a field of a node compositor. Once the digital editing action block is arranged at a compatible field within the digital editing user interface, the snap effects system can execute the digital editing action block to create a particular graphical effect according to the positional configuration of the digital editing action block within the node compositor. In turn, the snap effects system can save the action-block configuration within the node compositor and facilitate additional use and/or sharing thereof.
