I can't figure out the per-worksheet settings and the default settings around "Use class path of module" and "Compiler profile", and upgrading to 2018.2 apparently broke a lot of my worksheets. I think it's because of the class path.
The UI doesn't seem to let me change the class path on a per-worksheet basis: that's grayed out. The "Default settings" tab lets me change the default, but that's applied to all the worksheets in the project, it seems. Is this the behavior other people see? Does anyone know if it is possible to have different class paths for different worksheets in the same project?
