I click the + sign to add a new directory to search paths:
And all it does is add an empty folder with no way to set the path. I created my extension, and the whole time I thought my extension was saved where I created, I found out VS Code was looking in some other directory. So I deleted everything and copied to the directory I want the add on in, and now Code doesn’t know how to find it.
What is the point of the + sign if you can’t add a directory with it?
