The interface is fairly spartan; I suspect this is the first time this developer has had to design their own product. There aren't any bookmark thumbnails or colors. Your bookmarks page is just a list of several hundred mostly-identical items, and they don't have real search, just “filters”, so you aren't going to get relevancy ranking, which is a bummer because it's built into tools like Postgresql. Yet another bookmarking tool that focuses too much on the bookmarking experience and not enough on resurfacing and utilizing those bookmarks later.
Pros:Automatic categorization, push to devices
Cons:Dated interface, no thumbnails, poor search
