Ability to be able to have employee tab, ATS and Queries tab all open at the same time

When I'm adding a new employee and then get asked to create a report I have to come out of one area of people to go into another. I would ideally like to be able to have all options open so i can be available to get answers on all things while also entering data into peoples files. It would also help if im running a report but need to check something in employees, file what a file is called or how its labelled so i can get it added into my report.
