Upgraded to V19 and lost some of my Components categories

I recently upgraded to V19 and by doing that it seems that my Component selector changed. I’m not sure if I had an extension before and I’ve been trying to Google my questions but haven’t had any real success. Before the upgrade for example if I went to the Component selector and chose Architecture there would be a break down of subcategories: Windows, Doors, Etc. I would select doors and it would take more to the 3D warehouse and show me the doors made by the SketchUp team. This just made things a bit easier for me. I’m not sure if I had an extension that made this possible or some type of plugin. I’m just hoping someone might be able to point me in the right direction.

Thanks for the help!
