Want to keep up with tweets without leaving your tablet's home screen? Grab Plume for Twitter. Plume offers four different home-screen widgets, ranging from 4 by 1 inches to 4 by 4 inches. But initial size isn't a major issue here, since Plume supports Android's widget-resizing feature: With a couple of quick taps you can expand or shrink any Plume widget to whatever size you like. The Plume widgets provide a scrollable view of your Twitter timeline, along with options to view your @-mentions or direct messages. You can compose new tweets from the widget, too. Plume is available in a free but ad-supported version, and in an ad-free premium version for $3.
