Pukka update: 1.8

PukkaPukka, the light-weight Delicious client from Code Sorcery, was recently updated to version 1.8. This update includes bookmark searching from the menu-bar (a la Spotlight), full Applescript access to bookmarks, and the ability to drag and drop your accounts to reorder them (with the top one serving as your default account). It additionally includes improvements under the hood like code signing and similar improvements.

For details, see the Pukka 1.8 blog announcement. Pukka is probably your best bet if you want a desktop Delicious client (my favorite bookmark manager is WebnoteHappy, but sadly its developer does not appear to be actively developing it any more), and is a very streamlined way to save and access bookmarks, particularly with the introduction of searching.
