Subject: progress and suggested changes

I have been working on the prototype to add awareness of the user
environment and to implement more of the selection boxes. It turns
out that directory selection has been an outstanding problem for tk
for a long time. I did manage to find some code that will do it, but
I'll still have to do some adaptation to it.

One problem is that, since there is no directory selection dialogue in
tk, directory selection will look different from file selection. That
might be a minor problem, however.

Another issue is that I'm recommending a change to filter definition.
Instead of the current four choices (which take up six lines):
any subject, subject matches X, subject matches X and date before Y,
subject matches X and date after Y, I'm suggesting making the subject
and date independent choices. So the subject choices are any subject,
and subject matches X; the date choices are any date, date before Y,
date after Y. This will take up only 5 lines, plus it would allow
a filter for any subject to go with date before or after, which is not
now possible. (This is useful for splitting up a mailbox according to
date regardless of subject.)

I'll be implementing the subject and date browsers.

I'm planning on implementing a tab transition proc that can determine
what tabs have been clicked and determining program behavior. If we
want people to explore, we can diable everything on a tab, but still
let people look.

Anybody else have any thoughts. We seem to get awfully quiet after
