This was a feature I used A TON in RFactor 1 and GT Legends. and continue to do so in RF2. I believe GTR2 and Race 07 also had it and probably some other ones as well. Keep track of changes, what to maybe change, lap times, behavior, car/game version number (since physics change), maybe some FFB settings, certain things to look out for on track with regards to the track itself and/or handling, notes about long run performance, etc. It can really make a huge difference and goes hand in hand with just the simple ability to even save setups in the first place. It also helps a ton when loading a setup after joining a random session, or when servers constantly hop from track to track. It will take a bit of work with the U.I. but I'm assuming it should be quite straightforward since all those other games (RF1, GTL, etc.) have it. If anyone is wondering, I added the text in the pictures through Windows Paint just for a quick example. P.S. Sorry for the misspelling of Reiza. Can't edit the title.
