I have my loco decoders programmed with a "breaking delay" value (CV4).
At the moment, the "Stop" button generates a speedstep of 0 which is perfect in most cases; the loco decelerates gradually to a stop.
However, sometimes an emergency-stop (speedstep -1) is needed for one specific loco; to avoid a collision for instance.
The emergency-stop button currently available in the menu acts on all locos, but it would be nice to also have the option to emergency-stop one specfic loco without influencing all the other locos.
It seems logical to me that one solution could be to to add a long-press feature to the Stop button in which case the emergency-stop is activated.
Last but not least: thanks for all the good work; the app really works like a charm!!
