Would be nice to be able to start/stop/restart races with AUX switch. As is it is distracting to let go of radio, click on the start race, then get radio in hands properly again. DRL sim got this feature and I must say it is super convenient

It's already possible to do that with a workaround. You can map keyboard shortcuts to a switch/button on your transmitter using a software such as this:
Windows: http://joytokey.net/en/
Linux: http://www.lgdb.org/tool/antimicro
Mac: http://alternativeto.net/software/joytokey/?platform=mac
(Keyboard shortcut to start/stop/restart timed race is "t")
