How do I change the direction of page scroll (horizontal/ vertical) ?

Avaz's vocabulary -  Pragmatic vocabulary is supported by a horizontal scroll (left to right), to aid the natural and intuitive scanning of words from left to right. The vocabulary is displayed with a horizontal scroll. However, for specific language vocabularies (like India, Denmark and Australia vocabulary) Avaz versions have a vertical scroll (top to bottom)., retaining it due to the original versions. 

For Avaz versions earlier than version 4.0, the page had a vertical scroll (top to bottom). However for the later versions, (from 4.0 and above), the vocabulary is changed to Avaz Pragmatic vocabulary which is supported by a horizontal scroll (left to right), to aid the natural and intuitive scanning of words from left to right. 
 

Note:

1. If you currently have Avaz version less than 4.0, there is ONLY vertical scroll. 
2. If you have purchased Avaz version 4.x and above:

• there is only Horizontal scroll
• However, if you had purchased Avaz earlier and then updated Avaz (from an earlier version of Avaz (less than ver4.0) to 4.x: 

• your vocabulary will retain the original vertical scroll direction (top to bottom), so that there is no disruption for the child
• If you create a new page/folder under any of the existing folders, the new folder / page will inherit the same characteristic as the parent folder - i.e., if the parent folder has vertical scroll, the child folder also has vertical scroll.
• But if you create a folder under the Root folder, it will have horizontal scroll. If you wish to change this back to a vertical scroll, copy and paste this folder under any other existing folder that already has the vertical scroll. 
• If you do a Restore Avaz Pragmatic Vocabulary from the Settings, you will have the new horizontal scroll only
• If you restore an Avaz backup from any other app that is version 4.0 or greater, then you will get only the new horizontal scroll.
