I think it would be annoying if any player would make a new topic for his suggestion, so you can post here, if you want, some suggestion.
There's mine:
1. A command /current <ID> . I see lots of players asking "What's the name of your car" and things like that, so I think it would be helpful a command like that to see the name of another player vehicle.
2. A command /csave /cload (from CarSave | CarLoad). For example: you tune a car at /trans /arch /locolow as you want, with paint jobs, rims and others, then you type /carsave. And when you rejoin the server, come back from StuntWar, etc., to be able to get your saved car with /cload.
