* TODOS
  - Paket exec-path-from-shell, um PATH aus Linux auch in emacs zu haben
  - Smart mode line?
  - Theme
  - evil-collection or custom in init file?
  - Hydra
  - General
  - (defalias 'list-buffers 'ibuffer)  ;; change default to ibuffer
  - ido?
  - treemacs (for linux)
  - treemacs-evil?
  - treemacs-projectile
  - ace-window
  - windmove?
  - tramp (in linux)
  - visual-regexp
  - org configuration: paths
  - org custom agenda
  - org configuration: everything else
  - beancount configuration from config.org
  - CONTINUE TODO from config.org at Programming

* Header
Emacs variables are dynamically scoped. That's unusual for most languages, so disable it here, too

Start fava with fava my_file.beancount

It is accessable on this URL: [[http://127.0.0.1:5000][Fava]]
Beancount-mode can start fava and open the URL right away.
