I've noticed that if you open a page in NXT in a new tab in the background, or if you just open it and then switch your browser's focus to a different tab, the browser will not actual load the content of the tab until you go back to it. Is there a reason for this, and could it be fixed? It gets frustrating when you are trying to open several tabs' worth of information at once, but then you have to wait as each tab loads individually.
