Aescripts pt_ShiftLayers v2.4 Full (win, mac)

Shifts or staggers Chosen layers in time with a User-defined number of seconds or frames.

Some great features of pt_ShiftLayers:

Shift Selected Layers: Shifts all selected layers in time at precisely the exact same quantity. It's possible to change with a predetermined timeframe or have the initial in-point/last-out stage of the chosen layers leap into the present time mark.
Stagger Selected Layers: Staggers chosen layers at a time, offsetting each coating by a predetermined amount of Seconds or frames. Layers could be staggered beginning from the present time Mark, or the counter could be added to each layer's present moment. Layers are Sequenced in the order in which you pick them, so be conscious of this when you are Shift-selecting collections of layers.
