If you enjoy using Tweet Marker with Tweetlogix, you may be interested in checking out their new Subscriber Plan at tweetmarker.net. It’s a great way to help support the Tweet Marker service and includes access to a Safari extension for setting markers from Twitter’s web interface.
If you haven’t used Tweet Marker before, it can be enabled in Tweetlogix from Settings > Services > Synchronize. Just like placing a bookmark on your timeline, Tweet Marker makes it easy to switch between different Twitter apps without losing your place. When enabled, Tweetlogix saves the place of your home timeline, mentions, and lists whenever you press your device's home button to close the app. Your place is restored when you return to Tweetlogix and marked with a blue ribbon in the timeline.
