Version 2.3 of Core Data Lab features persistent column configurations for saved predicates, font size settings for grids, several predicate editor improvements, a few fixes and a lot of other enhancements.
Often when working with predicates, you are only interested in a subset of the available columns, and not seldom you want them presented in a different order. Hiding and reordering columns was already possible in previous versions of Core Data Lab. Starting with this update, the selection, order and sorting of columns of the main data grid are now saved as part of a stored predicate within the Core Data Lab project, when you save a new predicate or when you adjust an existing saved predicate. The Grid view subsection of the View data section in the Core Data Lab Help contains detailed instructions how to change the position, visibility and sorting of columns.
