Nautilus 2.16.1, Ubuntu 6.10

1. Open a folder window.
2. Double-click on the resizing grippy in the corner of the window.

What happens: Nothing.

What should happen:
*   For each of {width, height}:
    *   If it is possible to resize the window to exactly fit the folder
        contents' scope in that dimension, do so. For example, if the folder is
        in list view, and the total width of the currently-visible columns is
        less than the width of the desktop, resize to that total width.
    *   Otherwise (if the folder contents is too big in that dimension),
        maximize the window in that dimension.

This will aid spatial recognition of folder windows, as it will ease giving different folder windows distinctive sizes and shapes. Double-clicking on the resizing grippy is analogous to double-clicking on the edge of a column header to resize that column to the optimum width.
