Hey, thumbs up for this proposal!
On an average week there’s like 5-10 courses we play 90% of the time, so most of the filters currently available are not used most of time.
However practically every time before going out, we check the traffic levels at those regular courses and typically select the one that is least busy. And that is a lot of clicking just to open each course & check the traffic.
So if the Courses-view could be filtered straight off the bat to show f.ex. just the courses with low traffic, that would help a lot. Game changer as the OP said.
