RE: customize objects are in no useful order

[Drew Adams]

    What would be useful is to sort only group names, because often
    subgroups (except basic subgroups defined in cus-edit.el) are placed
    in the customization buffer in quite random order.

    Also it is useful to provide a key and menu item to change sorting
    order only in the current customization buffer, to make easier for
    users to change the order to alphabetical when needed.

You make good points (not just what I've quoted).

In some buffers, some of the options are grouped logically, and that's
helpful. In other buffers, however, especially large buffers with lots of
options, it is hard to see the logical grouping, even if it is present.

Perhaps there is a way to have the best of both worlds, programmer order and
alphabetical order, with a button to toggle between the two.

Alphabetical order is a "dumb" (suboptimal) ordering, but it can be helpful
when there are lots of options and you can't find what you are looking for.
