Hi Rodrigo.
I exactly understand your feelings.
For this case I always use importing project through .wsd file.
I describe the process:
- import the project in KDS

2. Select Existing Working Sets

3. Click on Browse

4. Browse the demo and find the .wsd file

5. Now you will see all needed libraries to your project

6. Now in KDS you will see all needed libraries

By this way you can import every demo.
I hope this helps you.
Best Regards,
Iva
