The folks who brought us "Beautiful Widgets" have now worked their magic with Twitter: Touiteur. Just hit the app store this morning. Free, and US/ $2.73 for Premium (multiple accounts, more). Beyond awesome! Slick UI, feature-rich and smooth functionally (Droid). Hard to believe it's a "1.0" release. I played around with it @ lunchtime, and can't wait to dig in again after work. But it seems to have every feature desired covered. Be sure to long-press on icons to reach em all.
