I use my primary timer in count-down mode. The sound warnings are tremendous. I like to have a warning if I have exceeded the time limit. I have been able to create that by calling wave files at the appropriate time in the timerV.jsn file.
The issue is that to do that you have to calculate the time elapsed from the initial time. That works on the first model that I set up. The problem is that the timerV.jsn file is a universal file. That means that the settings apply to all timers in all models.
Given that not all my models and timers have the same initial time set, this means that my over-time warning are not consistent.
I'd like to suggest that for count down timers, you can have further warnings based on the time past zero. That way the one file would work regardless of the initial count down time set in any timer and in any model.
