Twitter has released TweetDeck 3.0.2, which offers a notable interface redesign. A new icon sidebar on the left side replaces the previous top-mounted controls, offering a pair of buttons for creating a new tweet and for searching, and then a stack of buttons for each of your columns, plus three buttons at the bottom that expand the icons into text, open the list window, and access settings. You can finally rearrange columns by dragging their sidebar icons, and clicking a column icon focuses on that column, scrolling the main window as necessary. Some additional interface refinements are coming soon, but haven’t yet appeared in the Mac App Store. Once the next version arrives, you’ll be able to drag grab handles to rearrange columns as well, clicking a column icon will bring columns to the left edge if fewer than four columns are showing, and clicking a second time on a column icon will scroll that column to the top.

Mac OS X Services in Snow Leopard
Mac OS X Services let one application supply its powers to another; for example, a Grab service helps TextEdit paste a screenshot into a document. Most users either don't know that Services exist, because they're in an obscure hierarchical menu (ApplicationName > Services), or they mostly don't use them because there are so many of them.
Snow Leopard makes it easier for the uninitiated to utilize this feature; only services appropriate to the current context appear. And in addition to the hierarchical menu, services are discoverable as custom contextual menu items - Control-click in a TextEdit document to access the Grab service, for instance.
In addition, the revamped Keyboard preference pane lets you manage services for the first time ever. You can enable and disable them, and even change their keyboard shortcuts.
