On the WEB app when I edit a schedule the zone name shown is truncated to about 10 characters. But there is about as much blank space to the right before the "yes"/"no" button. Ten characters is a bit short, it was a challenge to rename my zones so that the displayed characters would be unique. Even with this editing I have to "know" my zones because of the text limit.
It seems to me that there is ample room to truncate at 20 characters, perhaps more, to make zone recognition more accurate.
