Can Refueling Sequence be activated on iCab?

I wasn't doing something wrong. Evidently, the Refueling Sequence is a functionality that has not been implemented in the iCab app. My guess--which is just that, a guess--is that this was an oversight. I hope that Lionel will address this omission in the next update.

I also hope that Lionel will increase the functionality of the two smoke buttons so that they replicate the Legacy feature of being able to set the smoke to Off, Low, Medium, or High. It seems that now, the two buttons just turn the smoke on and off. I think that being able to adjust the smoke level is an important feature. Of course, I'm not the one who would be doing the programming, but my uninformed opinion is that it wouldn't be difficult to do this. In the meantime, when the smoke is turned on via the iCab app, what level is it at: Low, Medium, or High?
