REQUEST FOR IMPROVEMENT Hi, just a thought but it may be already on the to do list hopefully. It would be good to be able to save the circuit settings for each engine you have so that the characteristics for accel, decel etc and sounds can be swapped over depending what engines you use on each circuit. I have 2 circuits with isolatable sections and 4 different steam engines large and small and their characteristics are all different and I don't want to have to keep changing the settings depending on what engine I'm using. Also save the engine type for the sound. If in future there are more sounds dependant on engine size/type it would be great. Well done, early days I know, being a retired software developer consultant I know what you're going through!
