May I suggest that in the next update you add some consistency to the event counters in the main rack on the right hand side.

Passed/Blocked/Marked/Scanned are all displayed in different order on different rack aps. Some have blocked before logged, some just the opposite.
It makes glancing at them impossible. It would be a step better yet if you would add color codes so that 'blocked' was in red, 'passed' was in green, etc.

Keep up the good work!
