Since you can only call on the Twitter API a certain amount of times per hour, would it be possible to show the number of calls left that hour somewhere in Tweetie (maybe in the bottom right corner)? Also, the ability to control how often Tweetie checks the API for different things would be nice (for example, if someone doesn't get a lot of Direct messages they could set it to every 2 minutes for regular tweets, and 15 minutes for DMs)
