I'm trying to set up Zoomify so it can only be used when HOLDING a spyglass.
Options on the image seem to be what I need them to be, but they do not work as expected.
What actually happens:
When I hold Spyglass and use Zoom it Zooms with spyglass overlay,
When I hold Spyglass and use it - the spyglass overlay is applied but spyglass' zoom doesn't work,
When I do not hold Spyglass and use Zoom it just zooms normally WITHOUT spyglass overlay (Changing Overlay visibility to "Always" doesn't change this either)

I have little experience with the mod so maybe I'm just stupid, but it seems like an issue for me.
