Regarding above "fuel screen" - een if GPS, OBD II, etc sn't automated now, it would still be nice to have as much automated/as simple as possible..
I.e. Date could be auto filled wth current date on carputer OS (but changable if desired for some reason), should auto remember settngs like fill up, and what grade octane, maybe when you hit vendor a box pops up with the various logos (chevron, shell, 76, etc.. and you could add your own if desired).
Just some thoughts..
