Subject: 27.1; [FR] Tie customize-theme to currently active theme by default
Date: Thu, 22 Oct 2020 19:27:29 +0300

Hello.

This is a feature request someone suggested me to make.

I am aware there is a good facility to interactively customize faces
(`M-x customize-face`) and on the other hand there's a lower-level
function `custom-theme-set-faces` which, I understand, can be used to
customize faces per theme.

It is very often that a custom face works for one enabled theme but if
one loads another, the style can clash.

I propose that `customize-face` would default to customizing faces that
will be tied to the currently active (or topmost on the stack) theme.

Many have light and dark themes that are often used and switched daily,
depending on ambient light conditions. Effortlessly customizing and
finetuning each theme would prove a nice way to make casual little
changes without messing other themes.

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I think that most people that customise a face want that face to be
exactly that way, and not tied to a theme, but I can see that it'd be
useful to be able to create a kind of "child theme" via Customize --
perhaps as a separate command.

I'm not sure how that would be most easily be implemented -- it'd be a
set of faces that should only be activated after a theme has been
activated, or something.  Has anybody done any work in this direction,
by any chance?
