Does it do multiple columns, too? With TweetDeck I tend to have lots of columns - all tweets, only best friends, dms, facebook and a running search. Would like to get rid of TweetDeck because it is the only Air application I still have.
YoruFukurou is great and I've been using it for more than a year but I already use Tweetbot for iOS on my iPhone and iPad so switching to Tweetbot for Mac makes perfect sense, especially if you're like me and obsess over synchronization and UI consistency.
