Hiding Time-Tracking Information
Power Scripts™ for Jira 2.5.2+ (server)
There are thousands of requests to hide the time-tracking information (e.g. internal costs) from customers.
You can do this easily with Power Scripts™ for Jira, however note that the information is still available when inspecting the page source.
All you have to do is to create the following script and associate it with the main LiveFields configuration on your project.
That's all. Your customers will have the panels and tabs hidden.
