Thanks, I really appreciate the feedback!
The original idea came from exactly what you described, having setup sheets in multiple locations and then trying to find the right one before race day.
Setup comparison and track-specific recommendations are definitely areas I want to continue improving. Mobile support has also been the main focus since most of setup changes happen right at the track.
Thanks for taking the time to check it out and for the suggestions. Please feel free to signup and check it out as well. I'm looking forward to seeing what features the community finds most useful as the site grows.
