[OS X TeX] How to split horizontally the PDF preview in TeXshop

[Vincent Verfaille]

Hi there,

When editing a quite long TeX document with TeXshop, I often wanted to  
see 2 full pages of the PDF.
This would be possible with a horizontal split (ie page A on left and  
page B on right), on a wide enough screen.
However, the current PDF window split is only vertical (ie page A on  
top, page B at the bottom).

Does anybody esle have the same need?
Would that make sense to add it to the TeXshop feature wish list?
Or is there any hack to do so with the current version of TeXshop?

Best,

Vincent Verfaille
