I would like to retain the ability to disable tabs, so that each file opens in a new window. It's so important in my job, I want all the pdf view in each separate window. I really hate the new version who don't be able to disable the tabs, all pdf are in a same window, it's so annoying and non productive. Bring back the option for giving the possibility to separate tab in many window for people like me who NEEDS in many windows.
