Is there a way to set up a document so that the text wrap default is different on one layer than on others? Or is this setting only possible to set for the entire document?
Also, I see there is also a layer option to "Suppress Text Wrap When Layer is Hidden". Is there instead some way to instead suppress text wrap whether the layer is visible or hidden, so that it doesn't affect the other layers?
In the prefs you can select whether text wrap affects all layers, or just text frames below the object that has wrap applied in the stacking order, which might do what you want if the text is on its own layer. You can also set any text frame to ignore text wrap in the Text Frame Options dialog for that frame or as part of an object style.
