I have 3 projects: "core", "test1", "test2"
they are located in different folders: core, test1, test2
folders test1 & test2 have symbolic link to folder core. This link is to allow Python to find "core" module.
I`ve created a project group, using option Folder of projects. As result I have 3 opened projects "core", which
reference to 1 physical project.
Please do not reopen project if it is already opened.
