Android File Transfer is the app I'm using on my Mac desktop to interface, so I'm assuming a Kindle question would go here.

Q: Where are the library files stored on the Kindle (the library where you would add canvases and brushes)?

I'm wanting to add to the basic canvas selection where it would affect the tooth based on loading a jpeg.
But I would also like to add brush packs and such.

Just finding out the parameters or limitations of the Kindle Fire HD app.

Thanks.

Question 2:
What can I disable to get it to not lag using a basic stylus when drawing a simple line.
