However, if someone decides to > proceed with this, I will try to support them as much that I can. I suggest to file a separate feature request bug report about this, and include in it the requirements for the display engine to support follow-mode. That is, given a set of windows that are "following" each other, what should redisplay do when certain display-related events happen. Then interested volunteers can implement that.
