In principle I like the idea of being able to work with a “master” grid. That’s something I wished e.g. for Qt Creator’s preferences dialog, where we use group boxes to group options, and these contain either something like what form layout does, or lists of checkboxes etc, or a mix.
Currently it is basically impossible to align the content in the vertically layouted group boxes.
