My car had hill hold assist as an option so I didn't need to add this.
I did switched the rear DRLs on as my car wasn't factory enabled.
I have disabled the stop/start system, and also coded the mirror fold on lock. As I have advance key I need to hold my finger on the handle lock pad a second longer for it to activate.
I had a play with the HBA activation/deactivation speed as I wasn't happy how it was factory set.
Changed the comfort indicator flash from factory set 3 to 4 flashes.
Also coded the panoramic sunroof and windows to close via the rain sensor, also checked I had full closure on locking/unlocking via the key fob.
I will spend some more time looking at all adjustment options to see what I can find, you could spend days on this.
