+1.

FWIW, Bookmark+ has had this for a decade.

Two options for this.  Uses predefined var `fringe-bitmaps'
for the choice.  (But really there should (also?) be a user
option for such a list.)

(defcustom bmkp-light-left-fringe-bitmap 'left-triangle
  "Symbol for the left fringe bitmap to use to highlight a bookmark."
  :type (cons 'choice (mapcar (lambda (bb) (list 'const bb)) fringe-bitmaps))
  :group 'bookmark-plus)

(defcustom bmkp-light-right-fringe-bitmap 'right-triangle
  "Symbol for the right fringe bitmap to use to highlight a bookmark."
  :type (cons 'choice (mapcar (lambda (bb) (list 'const bb)) fringe-bitmaps))
  :group 'bookmark-plus))

E.g., setting `bmkp-light-left-fringe-bitmap' to Jim's
`bookmark-fringe-mark' (symbol) uses that fringe bitmap.


And yes, it would be good to add a bitmap such as Jim
suggested to `fringe-bitmaps'.
