Implementing a Grid layout system would allow creating interfaces that is not currently supported through Flexbox.
In short this is because Flexbox is a one-dimensional system, while Grid is two-dimensional. This grants control over columns, which is especially useful in responsive web design. It is for example not currently possible to create an iterating container with a predefined number of columns and vertical direction (reading down). There are also several challenges linked with spacing in the current flexbox, that a grid-system would solve.

Is this currently on the roadmap?
This feature is requested on virtually all of our projects. It is possible to do this with CSS in Appfarm, but it is very cumbersome and not very no-code and easily maintainable. Webflow has an excellent, easy to use implementation of grid: Easy CSS grid layout module | Webflow
