Tweetdeck's got a gift for you today. No, unfortunately it's not fixed notifications, but it's still a step in the right direction. Meet the new, prettier tweet panel. It makes firing off 140-char screeds a little more pleasant.
Instead of the old, gross white box that would pop up in the middle of your screen, the tweet panel extends from the left-hand side as its own little column, and incorporates all your options vertically. All the same functionality is there—multiple account icons, scheduling, direct messages—but now pulling up the tweet interface doesn't plop a giant ugly box right on top of all the action.
There are a couple little functional updates. Uploaded images now have a thumbnail, for instance, and responding to multiple users is automatic. But mostly the changes are aesthetic, with a little added convenience on the side. The updates are slowly rolling out to web and Chrome versions today, with the oft-neglected Windows and Mac apps to follow. Surprise surprise.
