main window: allow pane to be shrunk left or right

Most GNOME applications that use a pane allow the contents to
be shrunk so the user can resize the mane to the maximum in
either direction.

This patch also slightly increases the default window size and
allows labels to be ellipsized to improve the default starting
layout and the behaviour when resizing the pane.
