Request to be able to highlight multiple layers so actions can be carried out on those layers all at once.
Example, hold ctrl and select (left click) required layers.
Right click on any selected layer to bring up pop up with various options ( delete, layer properties ) etc.
If you change the transparency then it does this for all highlighted layers.
Or even drawing or using the Eraser within the layer it carries out that action on every highlighted layer.
Moving highlighted layers: Move all to bottom/ top, if holding ctrl then dragging layers they maintain position.
Example you have 10 layers and you highlighted layer 1 and 5, you hold ctrl and left click layer one then move your cursor down so layer one is blow layer 3.
So now layer 1 becomes layer 3 and layer 5 becomes layer 7.
