;; toolbar-settings.el --- Tool bar settings  -*- mode: emacs-lisp; lexical-binding: t -*-

;;; Commentary:
;; icon name and item name must be the same, e.g. pepper
;; "/home/daniel/.config/emacs/icon/pepper.xpm"
;; defining toolbar items
;; emacs look into the data-directory to find files.
;; either copy global etc folder to local and overwrite the path to local
;; (setq data-directory "/home/daniel/.config/emacs/icon/")  ;; default "/usr/share/emacs/28.0.50/etc/"
;; or copy local files to global etc folder
;; then add item with name of icon name, e. g. pepper because of pepper.xpm
;; but before changing data-directory, better add local icon folder to the image-load-path
