hi, first of all thank you for having invented this software, I congratulate you it is as its name indicates it very simple and effective!
I think it could give us the time to accumulate with a reset, and a starting value * to change the nozzle every 200 hours of operation for example.
* I currently have 12 hours of impression on my nozzle and I would like that it is twelve hours are taken into account.
Thx.
