I am really, really impressed how much my workflow has improved now that I have an inbuilt webbrowser and pdf reader in the brain. I can comfortably read and take notes. A while ago I stopped putting notes into the Notes window, all my notes are separate thoughts. Interesting new connections pop up all the time now:-) I follow these connections and, of course, I lose the text I was reading before. Then I have to click myself back into the thought containing the text.
It would be wonderful if I could pin a text, a pdf, a blog, etc. The text would stay put in its window and would not disappear when I click on other thoughts. I imagine myself clicking a button in the tab of the attachment and then this attachment stays put. 

+1 here also. However I could see people doing this by accident and being confused, so I think it would need a identifier similar (but possibly more visible) to the tab color change when the tools area shows the content of a hovered thought.

Interesting request. Thanks for posting and I'll document for further review.

I’d like to add my support to this request please. [smile]

The inline viewer is great until … I click on another node and loose the current reading position in a pdf or html page if its a browser. My current workflow  is to create a secondary window for stateful content that is “relatively” static i.e. that is until 'I forget’ and … 

IMHO incorporating a setting/pin (and flag @Zenrain) for persistence and stateful content in a window would raise the bar on its usability signficantly.

Doesn't right clicking on the content window title area and selecting "Open Content in New Window" accomplish this?
