Easy Class Break is an extension for Chrome. It works with any break-time schedule. It allows you to check when classes overlap and when a walk is sufficient to make it to the next one. It will automatically check for classes that are not reachable by walking, or ones that are not in the plan (e.g. those that start in the next week). It also allows you to find out the next one in a sequence and when the previous one ends. It will also give you a warning if it finds a break time that is too short for walking to the next session, which is useful when the break time is planned for a meeting or a lecture.
