CVS is out of date. I will not update for a bit.
I am going to be quite busy the next few days, and I might end up squeezing out another bugfix releae (3.4.8), or proceeding to 3.5.0.
I think I figured out a way to do something quite nice, and I am a bit excited (If it works, you will be able to split any panel that contains a styled text control, so the document, or the prompt. You will also be able to add as many panels as you like in any direction.)
