Do you know what the Twitter API is missing? A way to sync the last status you read.
I use a Twitter client on my laptop (Tweetie), and I use another (Twitterific) on my iPod Touch. And sometimes I might use either Twitter.com or Twhirl when I’m on another computer. Every time I move between devices, I lose my place in the stream of incoming tweets. Any good Twitter client remembers the last tweet you read. The only problem is that little bit of information (simply the numerical ID of a tweet) is locked down to one device.
I propose that Twitter add a new API method that accepts the ID of a single tweet, and stores it. Then any Twitter client could request that information and use it to display the tweets from where you last left off.

It’s a little thing that bothers me, and something I’d love to see added to the API.
