There are a lot of software titles that are gearing up for Tiger (which is very worth the price tag, by the way) but none with quite the list of updates and bug fixes than Delicious Library. One of my favorite apps has been bumped to 1.5. It has a number of Tiger-centric features, and some welcome changes and bug fixes.
I really like the new way of selecting items once scanner or input. You can choose what country catalog to pull the information for. This is a great UI enhancement. The list of possible matches also does not take you to another window like in 1.1. It now displays the list of possible matches with the rest of the Enter Item options. This cuts down on mouse clicks if you have to go back or need to manually edit something. It is a small, but nice touch.
The edition of correctly sized PSP and DS game boxes is also nice.
I wish I could rearrange the shelves. I am also hoping for a nice web export that has more options then DeliciousExporter, although that does a heck of a job as it is.
