Staircase is a tool for After Effects that allows you to quickly stagger, sequence and randomise blocks of layers.
Divide your layers into separate blocks via block size or via label colour. Hovering over the UI will highlight what labels are selected.
Offset layers individually, or control inside and outside the blocks.
Staircase comes with some great additional features like staggering based on position, adding easing to each block and fading between blocks.
