It's nice to be able to meet & communicate with the developer of a train related software program.
Your download page is easy to understand and answers most of the questions one might ask.
One track system I do not see that is not on your list is 3 rail Standard Gauge. There is a resurgence
of interest in original & reproduction Standard Gauge Trains, so including it would be helpful to someone
planning a Standard Gauge Layout, beyond a simple oval of track.
Thanks for sharing your baby with us.
Happy Rails!
