Hey @nick.carroll - far as I can see it’s not possible to dynamically change the min width of column setting for a RG via a conditional.
This would be useful for creating this kind of behaviour for RG cells, changing from, for example, 4 to 2 columns below a certain page width.
Without this conditional the columns will always go 4 > 3 > 2 > 1
Great work on the engine!
