I've been using Delicious Library since version 1.0, and while 2.0 was an all-around solid update, I always felt I needed to temper my praise for it due to the horizontal details pane. In today's world of widescreen monitors, that was pretty much the most boneheaded UI decision I have ever seen, especially since it worked before.

Well, it is now FIXED! That speaks well of the developer--willing to listen to complains and re-do a major UI feature in a .x update. From the user's standpoint, it's now both fast AND usable.

The other substantial fix in 2.1 is that Japanese product searches work, which for those of us adding older imported books is a Very Good Thing. It also seems to have fixed the issue where books with a size included were not sized proportionately relative to each other, but I haven't tested thoroughly.

Finally, 2.1 seems noticeably faster to me, though it could be placebo effect. The only thing resembling an issue I have now is that I appear to have ended up with a couple of duplicate items after the 2.0 to 2.1 update, though it's possible they existed before. This caused me to think "gee, a "find possible duplicates" feature would be nice, but it's far from necessary.

All in all, this is software done right--feels good, looks good, works good, and it's fun. Usually I'd be looking for excuses not to deal with filing and cataloging, but this is one situation where it's so much fun I'm <i>looking for</i> excuses to do it. And, hey, knowing which friend has which DVD is certainly useful.
