"Blend If" indication in Layers Panel

I mega second that!

Seems like a good idea.

I agree with this. And yes thats a good solution Charles. I think maybe one additional master row above "effects", with the Blend-if attributes listed. Double clicking brings up the Options, and toggling the eye toggles any blending (including layer effects) off. I don't know why it wasn't always implemented like this to be honest, it would be more logical that way.  

When 'Blend If' is used there is an entry in layerEffects this is 'scale', unfortunatly scale is used in other effects so a script can't tell if Blend If has been used on a layer, except when no other effects have been used on that layer.

It would be a great idea if they were shown as you have them.

Here is a script for you to play with, best I could do.

#target photoshop
hasBlendIf();
function hasBlendIf(){
if(!documents.length) return;
var ref = new ActionReference();
ref.putEnumerated( charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") ); 
var desc = executeActionGet(ref);
if(desc.hasKey(stringIDToTypeID("layerEffects"))){
    desc = executeActionGet(ref).getObjectValue(stringIDToTypeID('layerEffects'));
    if(desc.hasKey(stringIDToTypeID('scale'))){
    if(desc.count == 1) {
        alert("This layer looks like it has 'Blend If' applied.");
        return;
            }else{
                alert("This layer may have 'Blend If' applied.");
                return;
                }
        }
    }
alert("This layer does not have 'Blend If' applied.");
}

Yes, it would be very welcome! Was it Julieanne Kost or Katrin Eismann that asked for it too?
