Its a good idea, but like you said - a lot of wasted time is lost if the tram is out in mid flight.
I'll be honest guys - I REALLY don't want to support tram right now (if ever).
Its never been a popular map online or with me, and I have SO many things I need to work on ATM. My plate is full - I wasn't joking when I said I had over 30 items on my TODO list.
Your idea for buttons is good, and similiar to what I had thought of doing for Fritz. However, for the time being, I have disabled most of the useless movers on the default maps (check out BASE and ASSAULT for examples), that were adding nothing to the gameplay.
