Allow several views of the same file

[humdingerb]

It's often useful to view different sections of a file side by side. Pe and other editor use a little splitter-widget above the vertical scrollbar for that. Pe is limiting that to one split, i.e. you can only see two locations of your file.

I wonder if it wouldn't be nicer to make some sort of clone of the entire window. People could then re-arrange any number of views on their file horizontally or vertically, and use S&T to stick stuff together.

Of course actions in one window have to effect their clones, i.e. text changes have to propagate (but without scrolling, e.g. ini case you inserted/deleted lines). Such cloned windows should be easily recognizable. Watermark? Slight tinted background?
