We used to store layout ID's of grid styles before which caused all sorts of trouble whenever an update was pushed. Layout ID's are generated at compile time according to alphabetical order ig, so if a layout is added or renamed, it will cause layout ID's to change, which resulted in either a Different layout than the one user stored, or totally random layout or a crash. So to counter this, 0-6 constant ID's are used to save Grid Styles which should result in stable updates.
