Latest Chromium builds have undergone a major overhaul in the bookmark management section and these changes can be soon expected to be brought into Google Chrome.
The most notable change is the introduction of a bookmark manager (which looks very much similar to the Firefox bookmarks library).
Chromium also get the capability to Import from HTML and export to HTML formats. It can now import your bookmarks in Google Bookmarks. Currently, Chromium bookmarks are not synchronized with the Google Bookmarks after an import.
