Advice
For the best results it is advised to work from within a workspace and to add all the project dependencies to the workspace, such as the root path for Core/Classes and Engine/Classes
And even better, add the scripts .u and .upk content folders to the workspace this will make the extension aware of such packages in indexing and auto completion (but not its contents yet)
