Lima,
I can address these right now:
Have some "lashed up" engines where the grade crossing button is eliminated. ??
This one's been asked and answered in the past.
That's the way it is because, of necessity, lashups have a reduced set of soft keys. That isn't going to be changed any time soon.
Is there a fix for the "quickspeed" which comes up during fast scroll?
There si no fix required. If you don't like the feature (I, personally, use it all the time), just turn it off: Menu?system/Remote Setup/Quickset Speed and press the OFF soft key.
Will we be able to eliminate the "inactive engines" section?
I don't see how that would be possible. It's used by the READ command and the ALL ENGINES command.
It's also used by the Lashup function, however, that's one place I'd prefer to se the Inactive Engine List not used.
When will the next software update be out?
Good question, however, it's been on the list for a while.
If not already done, select directional or all for horns/whistle on a lash up?
I have no idea what that means.
And possibly a MTH weblink to print out a code cheat sheet for guests?
I have no idea what that means, either.
