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.
