Feature Request: Lock Alpha Channel for all Layer (Preserve Alpha)
Feature Request: Lock Alpha Channel for all Layers (Preserve Alpha)
As for now, 'lock alpha channel' in GIMP need to be done manually for each layer, so for example if I want to lock alpha channel of 10 layers, I need to manually check/toggle the 'lock alpha' option on the layer dialog for each layer. And unlike layer visibility (the eye icon), it seems I can't lock alpha channel for all layers.
In Krita this feature is named 'Preserve Alpha'; where all alpha channel will be locked temporary (it will be reset each time a new file is open). And there is a keyboard shortcut to toggle this option on/off.
