currently the lister viewer pane can be aligned on the right side and on the bottom of DO.
Presumably this option does not exist already, would it be possible to add a third option to display the viewer inside the lister on the bottom?
When displaying e.g. a PDF file, the view is very small when the file is shown on the bottom. If I display this file on the right side, the size is too small, too!
Hence, when displaying a file inside a lister, on bottom, it would be way bigger and better readable.
Moreover, this additional options allows, in case of a dual vertical layout, to view two files at once.
