I know that rapportive currently works with the verticle/horizontal split however its impracticle. I have widescreen monitors and if I could use vertical split it would be much more practicle for use of space. However when rapportive is being used for verticle split it takes up too much space on its own and makes the size of the email being read to small in width. I can honestly only use vertical split if I disable rapportive. It would be great if rapportive could recognize when verticle split was enabled and reposition itself to become a horizontal bar that is positioned at the top of the email instead of the side. This would be much more efficient in regards to screen usage.
