I've been frustrated with the new way dragging a document tab to make it a seperate window forces it into a split screen first, and then I have to grab the tab again and the second time it actually makes it a new window. I'd like to be able to toggle that feature on and off (I'm sure it works for someone's workflow). Additionally, the document window edges often hides under the menu and/or below the edge of my screen. This is frustrating because it makes it hard to scale the window if the right hand corner we're meant to click on to change the window size is outside the visible screen area. It's not that I never want to be able to push windows past that "off screen" area but when I'm trying to pull a tab into a new window then I want to be able to adjust it without fuss.
