Hi there, think it would be beneficial to have a little button near the setups in pits which allows you to search through your setups because i have lots of setups and think it would be quicker if there was a little search bar.
Have you tried naming your setups and sorting them by name instead of by date?
that works with me. All my setups have the track name so i can easily identify them and use them. For example, in fern bay black reverse, i have it named "FEB Rev".
Even if it is for a long named track such as south city long or south city town course, i use "SOL" and "SOTC" respectively. It also works for "KYN" (Kyoto National) or "KYGP" (Kyoto GrandPrix).
Adding to that i usually put a WRZ or WRY so i know which is the fastest and in what version i performed the best lap time. WR stands for world record for me to know i can make a really fast laptime, and Y or Z to version in which i performed that really fast laptime.
