PowerShell, ShowUI and the Twitter API–Part 2

Part 2 builds on the first 30 lines from PowerShell, ShowUI and the Twitter API–Part 1 (Check out the video tutorial for building it) and positions the script for the next set of steps.

More updates coming soon.

Updates

This version lets you view multiple Twitter search feeds. Type in a search and press enter and another column is displayed. You can delete a column too.

PowerShell Code

Download it HERE from my repository. Download ShowUI.
