Chrome Ext for Organizing Bookmarks?

There are so many links that I'd like to save, but built-in bookmarking features from browsers like Chrome are bare and not easy to use do to the nested structure. What I usually do is save links in the Notes app but does not scale well. What I'm looking for is a chrome extension that allows saving the current webpage with a click of a button, grouping hyperlinks by subject and also provides an intuitive GUI for access. Does such a service exist?
