~/.modular/modular.cfg's setting mojo.import_path can take comma-sep values to identify multiple import paths. The default value is something like:.mojopkg files (like stdlib.mojopkg, algo, math, etc). As the video says, you can add another path, like this:/path/to/packages/ is where I direct the "package" command's output. E.g., mojo package SomePkg -o /path/to/packages/SomePkg.mojopkg. As a result, I can do:.mojopkg file into every project that uses it.[mojo] and a [mojo-nightly] section in the file ~/.modular/modular.cfg. If you want both stable and nightly to import from the same dir, then you need to add ,/path/to/packages to both sections' respective import_path setting.
