http://reederapp.com/ WOW!!! The v1.2 update seems to address almost every requested feature, Twitter support, multi-line titles, swipe to star/read/unread. All wrapped in the most gorgeous user-interface - competition well and truly knocked for dead now What's new in Reeder 1.2 New - In-app Twitter support - Pinboard support (http://pinboard.in) - Mark as unread - Slider control for article list items (slide to left to toggle un/starred and right to toggle un/read) - Multiline titles in lists (for headlines) - Order by oldest first (see Settings.app) - Non-blocking sending/sharing (Reeder can be used while posting to Twitter etc.) - One-tap sending to Instapaper/ReadItLater - Visual feedback for (un)starring/(un)reading/(un)sharing an article - Sync status bar: tap to minimize, tap the sync icon to maximize Fixed - Unread counts were not always correct - Image squeezing - Open iTunes links with iTunes / App Store
Almost perfect, just wish you could refresh individual feeds in an adhock manner rather than the whole thing.
Recommend contacting the author from his site - he was very responsive when I last emailed him, enjoy Reeder!
