Re: bad UI defaults

[Richard Stallman]

    I gave two, one was to use :options which will give a checkbox [ ]
    instead of an [INS] button.  The other is the one below.

I just tried that, and what I got was an INS button plus one element
which I could enable using [ ].  That element refers to None and None,
and I cannot find any way to change them.  What is its purpose?

I think this interface is quite confusing.

    It does sound like you have a general problem with the editable list
    widget UI, at least for empty lists.  That affects a lot more than
    alists. 

Yes, in general, though how bad the problem is may depend on the
situation.  It would be really good to find a better interface for
this.

For most alists, the order does not matter.  So imagine that
there is a dummy element at the front.  The dummy element
has slots to fill in a car and a cdr to make it a real element.
If you fill them in, a new dummy element appears automatically.
