Add checkbox to mark correct constraint

[AndriiPetrovDev]

Please add a checkboxes to mark constraint as correct. It' ll help to figure out the problem whet there are more than 15 constrains

Thanks for raising an issue. Just to check I understand properly: It would be useful to add a checkbox for each constraint, so that a user can mark each constraint as correct as they look through the list. Or were you hoping that the website would automatically mark the constraints (e.g. unchecking the constraint that Auto Layout decided to break)?

From context, it sounds like the former. A checkbox that would dim out constraints would make it easier to focus on the ones we haven't checked yet.
