-Ease to use.-Multiple filters-Easy sorting options such as date modified/date added etc.-Integration into Chrome omnibox so you can search across all sources at once.-Quick view option that shows more data than what's actually visible if it were expanded.-The ability to mark items read without having them downloaded makes this an excellent way to manage my reading list! I wish there was integration with Calendly because not being able to set up recurring tasks would be very helpful, but alas, no complaints about functionality. This works well enough though, especially since most things we want done online nowadays have some sort of "bookmark" feature built right in. It does tend towards showing too many results compared with how much space is left after filtering out junk like adsense links.
