  # spacious-padding for GNU Emacs

  This package provides a global minor mode to increase the
  spacing/padding of Emacs windows and frames.  The idea is to make
  editing and reading feel more comfortable.  Enable the mode with `M-x
  spacious-padding-mode`.  Adjust the exact spacing values by modifying
  the user option `spacious-padding-widths`.

  Inspiration for this package comes from [Nicolas Rougier's impressive
  designs](https://github.com/rougier) and [Daniel Mendler's
  `org-modern` package](https://github.com/minad/org-modern).

1.1 Enjoy the optional subtle mode lines
────────────────────────────────────────

  The new user option `~spacious-padding-subtle-mode-line' makes mode
  lines more subtle. It does so by removing the background and adding an
  overline in its stead.

  By default, `spacious-padding-mode' does not refashion the mode lines
  other than adding to them some extra padding (per
  `spacious-padding-widths').  The user option
  `spacious-padding-subtle-mode-line' does change the mode lines so that
  instead of a background they only have an overline, while preserving
  whatever padding is in effect.

  The value bound to `spacious-padding-subtle-mode-line' is either a
  boolean type or a plist. If it is non-nil, use the foreground of the
  underlying mode line face to derive the color of the overline.

  If the non-nil value is a plist read the following keys to determine
  the exact style of the overlines.

  • `:mode-line-active' refers to the active/current mode line.

  • `:mode-line-inactive' refers to the inactive/non-current mode lines.

  Each key accepts either a face or a string representing a color as its
  associated value:

  • The face is an unquoted symbol, such as `success' or `shadow', whose
    `:foreground' attribute is queried to extract the desired color
    value.

  • The color is a name among those listed in the output of the command
    `list-colors-display' or a hexadecimal RGB value, such as `#123456'.

  If the key is missing or its value is not one of the above, fall back
  to reading the foreground of the underlying mode line face to
  determine the color of the overline.

  Examples of valid configurations:

  ┌────
  │ ;; Use the foreground of the underlying mode line face to determine
  │ ;; the color of the overline (e.g. the inactive mode line has gray
  │ ;; text, so render the overline in the same gray).
  │ (setq spacious-padding-subtle-mode-line t)
  │ 
  │ ;; Use the foreground of the `error' face (typically a red hue) for
  │ ;; the active mode line's overline.  For the inactive mode line, fall
  │ ;; back to the foreground color of the underlying face (as in the case
  │ ;; of the t shown above).
  │ (setq spacious-padding-subtle-mode-line
  │       '(:mode-line-active error))
  │ 
  │ ;; As above, but now use the foreground of the `shadow' face for the
  │ ;; inactive mode line.
  │ (setq spacious-padding-subtle-mode-line
  │       '(:mode-line-active error :mode-line-inactive shadow))
  │ 
  │ ;; Use color values directly.
  │ (setq spacious-padding-subtle-mode-line
  │       '(:mode-line-active "#0000ff" :mode-line-inactive "gray50"))

1.2 Expanded the documentation
──────────────────────────────

  The `spacious-padding' package now comes with an Info manual. When
  looking at the source code, this is done in the `README.org' file,
  which the GNU ELPA machinery automatically converts to Info. A change
  log is also provided.

  The package is stable and works well. This set of changes expands the
  concept of “spacious padding” to more user interface elements, namely:
