Possibility to enable/disable buttons "pause" and "reset" in the "Billing and timelog" section - Community / Feature Request - Deskpro Support
If you want to measure how much time agents spend working on tickets than the system should calculate the time and agent in this case shouldn't edit time. Because there might be risks of fraud when agent spent too much time working on ticket and he can easily delete the time from the time log. Or when agent will press "pause" button and goes to drink coffe or something else.
