Since I am using the timer in a country where English is not the primary language, I find that some customers do not understand that they can "finish" their session by clicking the "reset timer" button.
I think if it was possible to change this to a red "X" button instead, it would be more intuitive and the customer would be more likely to click the button instead of just leaving the workstation with remaining time, and then asking how to close it.
Thanks.
