Hi!
I've been using Tempo plugin for worklog purposes. It has a neat feature called "Tracker" looks like this:

After you finish your work on issue click stop and this window pops up:
Problem is users can actually change worked time value and also user value. Is there a way I can disable editing of these values? Or maybe even hide these fields from this window?
I also need to stop the timer when user's shift ends? (Based on work calendar either 18:00 for weekday working users or never for 24x7 working users)
