Don't take this personally, but I don't see a point in "designing" configs like these, let alone completely new venues with paint (which is the uttermost stupidity). If the devs would want to make new some configs, I think they have enough talent to pick the best new routes on their existing venue without the help of 2nd class MSPAINT artists.
Same goes with the car suggestions. Of course I can't speak in behalf of anyone, but at least I have this feeling that giving endless combination of the basic specs like weight, power, drive train etc. can only interest other daydreamers and contributes nothing to the devs.
:doh:
EDIT: UnknownMaster, I wasn't referring in your actual paint skills, but using mspaint as a track design tool in general instead. Your red line was just as good as anybody elses
Could be made available as an optional "carrousel" variation of FE Black and Fe Green, so we could choose. They are just 3 more corners, not enough for a proper "new" variation IMO, but could do it as an optional "carrousel" version
