Google has a history of improving old features and this is another in that vein.
The old bookmark manager shipped within chrome has been augmented by an new app available in the Chrome Web Store.
I think we can look forward to be shipped with new versions of Chrome in the future.
The new app includes a crisp visual look with pictures from the favourited website rather than the old style that looked the Windows 3.1 File Manager. Smart features are built in like Auto Folders that attempt to organise your bookmarks into like categories.
I actually like it!
