You can use modules from anywhere in the more recent (for a few years I think) versions. and you get options:
You can drag and drop a module, or use the menu: Project/Add Existing Module. You can obviously still organize them in one folder and link to them if you want to.
The shared modules feature, set under Tools - Configure Paths, still works. If a linked module is not found then the IDE will look for it in the project folder and then in the shared modules folder.
