Tvider Pro? It sounds interesting... I'll give it a shot
As far as I can tell, it doesn't actually integrate with your twitter account the way most clients do. It seems that it is only useful for adding media to tweets.
On another note, twicca has so far been my favorite. I've tried Twidroyd, Twitter, Touiteur, Hootsuite, Tweetcaster, Sobees, Seesmic, Swift, Tweetdeck, and various others that I honestly can't remember. I keep coming back to twicca.
One reason I do is that I get a LOT of links from people I follow, and so many of the popular clients can't open links in new tabs. The only ones I've found that do so are Touiteur, Tweetcaster, and twicca. Anyone know of any others with this functionality?
