When a layer is locked don't ask me if I want to unlock it. Instead give me a drop down list of all the layers to choose from
Usually when pasting something in Illustartor if the layer is locked it means I didn't select the right layer. If I could choose which layer to paste to I wouldn't have to cancel, select the correct layer and paste again
Also, take a look at this request an vote if you find it useful:
An option to choose a layer to drag into, lock/inlock a current one, seems like a more approachable idea than holding a hotkey... But I won’t mind in having both ways.
Sometimes when I want to separate complicated artwork into layers, I select the artwork to move, then start dragging the Selection Indicator (colored dot) in the Layers window, only to realize that the target layer is locked. Then I have to unlock the target layer, and re-try dragging the Selection Indicator.
It would be great if I could simply override the lock on the target layer by holding a modifier key, Command/Ctrl for example, then releasing the drag.
