Hi John,
For now, customization of the columns is not included from within ATVO. However, you can use custom / override CSS styles to hide columns. If you look through the html of the web page you can see that each column has its own class / name assigned, for example "cdk-column-results-iRating". You can add your own CSS style to this class, for example to set its width to 0 or something. You may need to add "!important" to override any other styles. I'm not an expert in CSS so that's probably an ugly solution but I've seen it used and it works :)
