I'm not sure why people don't understand that an "In Progress Only" checkbox will just make queues WORSE. Anyone actually FOR this checkbox I'm almost positive is a healer or tank main who actively "In Progress" fishes...the only one a checkbox like this benefits IS the "In Progress" fishers. Every DPS who queues for a new instance gets much longer queues thanks to the tanks and healers opting to check "In Progress" for quick tomes. Even if only 10% of tanks/healers opted for that checkbox it would have a pretty hefty effect on queue times.
