Changing the size of the Layer Thumbnails

I’ve only recently subscribed to Optics 2022 and am watching at lots of YouTube vids. I notice on quite a lot of them that the layers Thumbnails are quite big. I can’t find anywhere where I can change them. Can anyone point me in the right direction please? Thank you.

Welcome @annettecrook22 Open the Silhouette preferences and change the Thunbnail Size.

Hi. I had tried that. It only changes the size of the Filter thumbnails , not the Layers.

Sorry, I missed the part about the layers. There is not currently a way to change the layer size.
