RE: Reset buttons in Customize (Was: Bug, probably related to Custom Themes.)

[Drew Adams]

    However, an even better simplification is what I previously suggested:
    do away with the concept of "set for current session", and make
    Customize save automatically.

No, please don't do that. I just scanned your message, so forgive me if I
missed something, but I definitely don't like this part.

It is very useful to use Customize to, say, change a face and try it for a
while, without needing to remember what the previously saved value was in
order get back to the original setting. Especially if you make multiple
Customize changes, keeping track of all such changes manually and reversing
them would be a pain.

This is one of the *advantages* of Emacs's treatment of
preferences/settings/options over the treatment in other apps.

I agree that the Customize GUI needs reworking, but 1) not before the
release and 2) getting rid of being able to make non-persistent changes is
*not* a change we should make.
