I've been using 1.5.6c and was looking to move to 1.5.7b.. I have been using a ColumnGridLayout Addon for awhile. It's not too friendly after PHP 7.0..
His comments are that from 1.5.7 and on, it's an included feature.

Was it added? I don't see it, in the code I see some mentions to a Column function.

Thanks for the help, I'm really like the new updates!
