In my work I open and compare and edit multiple documents at the same time, this used to be easy because each pdf opened separately on one click, so I could very quickly have them all open and work between all of them at the same time using alt/tab between them all quickly. Now though pdfs all open in the same window mimicking an internet browser. So you have to click on each and then drag it out to a different part of your screens before you can start alt/tab-ing between them. It's slowing me down and I can't be the only one who finds this unnecessary extra stage to getting on with my work annoying.
