It’s now possible to search for a material by name with this free SketchUp plugin: Material Browser. In bonus, with this plugin, you can import a material from Texture Haven or CC0 Textures in 1 click.
Hi Samuel! Here to report that there might be a small issue with your fantastic plugin: if the material name includes the character “-”, the search engine fails to find the material.
I noticed because I have a library of NCS materials which typically are spelled like NCS 2070-Y80R (so there’s the “-” included).
