;;; module-org-notebook.el

;; This transforms Emacs+org-mode into a notebook application with:
;;   + Custom links for class notes
;;   + Shortcuts for searching org files
;;   + Shortcuts for creating new notes (there's org-capture, but this is suited to my
;;     workflow)
;;   + A simpler attachment system (with auto-deleting support) and drag-and-drop
;;     for images and documents into org files
;;   + A pandoc-powered export system
