Trying to install Ardublock.
The default setting for Arduino (as per preferences in File) is: /home/charles7/arduino
When this folder opened only 2 folders present. Libraries and my first sketch.
For Ardublock I need to open a new folder within the 'Sketchbook' folder - but there is no 'Sketchbook Folder'
Why is the sketchbook folder not there by default or do I create a Sketchbook folder with in libraries?
