;;; Commentary:
;; Helm interface for Chrome bookmarks.
;;
;; Warning: Multiple bookmarks with the same name will be overridden.
;; This restriction is for better performance. If we use Bookmark IDs with
;; candidate-transformer, then the speed would be quite slow.
;;
;; It's also possible to scan through urls of the bookmarks.
;; To do so one need to customize helm-chrome-use-urls variable
;; for the helm-chrome group or just set it's value in config file:
;; (setq helm-chrome-use-urls t).
;; Then reload bookmarks using function helm-chrome-reload-bookmarks.
;;
;; Warning: On a big number of bookmark it may be quite slow.
