In shader editor , how can i see the preview of the shader or any nodes without it's being applied to objects ? something like 'viewer' node in compositing editor. Right now if i have lot of 'image texture' nodes in the shader editor, i can't really tell what it is until i connect to the shader network or i have to zoom into the node and check the file path then view it in image editor ? this is really slow. when i select image texture node , should be a preview in the side panel or anywhere else to see the thumbnail. Any tips ? is there any better way to do it ?
