Planner updates
Planner: Improved scheduling & better real-world flexibility
What’s new:
Planner now allows overlapping schedule entries, removing hard blocks when conflicts exist.
Planned threads show a conflict indicator when schedules overlap, so conflicts are visible but not blocking.
Scheduling is now available in 15-minute increments.
Improved error handling when scheduling outside of work hours.
Why we're excited:
Real-world schedules aren’t perfectly clean—technicians often juggle overlapping work, and last-minute changes. These updates make Planner more flexible and realistic, giving teams a more wholistic view of their day without blocking progress, while still clearly surfacing conflicts when they matter.
