I think the general advice here is that searching for "startup" and "node" would have given you immediate results, rather than having to wait for a response.

I searched for this script but couldn't find it, but I'd like to be able to start MM with the Music Explorer Tree highlighting a specific location. When I start MM, the Library tree item is highlighted. Instead I would like it to open with the following node open: Library -> Artist.

- There was such a script for this and you merely right-click which node you wanted the program to open on and select "Set start-up node".

Thanks
