Important Notice

To achive a smooth scrolling result without shaking or weird movement, the number of data cells loaded at initialization is relevant to the width of the scroller as well as the total new cell data added each time it receives new data.

Total Required Initial Data Length = ( Total visible cells ) + ( New cells added each time) * 3

This is calculated automatically and an alert screen appears when more data is required.
