Delicious Library (Hah, you thought this was about food!) is a cool app. It’s pretty much the only game in town, and has also long been considered one of the premier mac apps in terms of visual style and workflow.
Where are the basic features though? Like secondary sorting characteristics? I really want to go through all my books and tag the “series” they belong to, but as delicious doesn’t sort “Series within author”, it’s kind of useless. This is especially annoying because the way core-data predicate searching works should make this decently easy to accomplish. iTunes has it (Album by Artist), and it’s really kind of an intuitive thing now that people are going to expect. (I’m actually really annoyed at Delicious Library right now, just because of this sorting issue!)
Here’s one of the downsides in working on cutting-edge platforms like Mac OS-X, iPhone App-Store, or the edge of webapp development. It’s a reaaaaally fast moving target. A feature that even a year ago would have been amazing, is now a major defect in your software if you don’t have it. You’re going to have to spend a lot of time chasing the target, and using whatever is left of your day to get ahead and innovate on your own.
This makes me wonder about doing development on any of these cutting-edge areas. I don’t know if I have that much time!
