AP has nice function - "Repeat <last used filter>", Ctrl-Alt-F by default. The greatest part of this feature, that you can do some filter on layer, then select several other layers and and call "Repeat ..." - and your filter will be applied to every selected layer, very effective.
There is also warp tool. It also can be repeated - so you can select part of image, do warp on one layer and repeat exactly the same deformation on another - BUT if you select several layers at once, repeat will work only on the active. Not on each layer, as with filters. So if you have several dosens of layers, that needs the very same warp action applied - you have manually choose each and press Ctrl-Alt-F... very tedious.
Please, make "Repeat warp" behave on selection in the same way as with filter - i.e. repeating automatically happen on each selected player, not only active one. For now this feature looks bugged, when some actions auto repeated on all layers and others not.
