I know, this should go in the Suggestion Forum, but I think this would be a really cool idea. suppose I have a two panel display with the windows vertical. Both panels are open to the same resource. Assigning the one on the right somehow as "reflow" which would pick up where the left hand window leaves off would essentially create a two-page view. The "Reflow" option would only become available in the right hand resource's context menu when this setup has been established. Or, better yet, right clicking on a resources tab would show the option "open this resource in a new floating window in reflow mode" I know two page display is coming to reading mode, but I know there will be times I will want two page mode without going into reading mode, and this seems like it would be far easier to code, at least to my knowledgeable self.
