The item "Adding items from folders" in the context menu of a C project allows to add folders to the source tree of the project, i.e. not items from folders, but the folder recursively. The current name implies that the folder itself isn't added. Naming that item "Add folder" or "Add folder recursively" is much more intuitive.
