PowerCommands for Visual Studio 2008: A free set of useful extensions for VS 2008 that add a bunch of cool features to the IDE.

One of the new features in version 1.1 is Enable/Disable of each power command via the Options dialog. This new feature was actually the idea of a developer who downloaded version 1.0 and then posted this new feature suggestion in the Issue Tracker section of the Code Gallery project.

Below is a list of the new commands in version 1.1 (now 23 commands total):

Enable/Disable PowerCommands in Options dialog
This feature allows you to select which commands to enable in the Visual Studio IDE. Point to the Tools menu, then click Options. Expand the PowerCommands options, then click Commands. Check the commands you would like to enable.

Format document on save / Remove and Sort Usings on save
The Format document on save option formats the tabs, spaces, and so on of the document being saved. It is equivalent to pointing to the Edit menu, clicking Advanced, and then clicking Format Document. The Remove and sort usings option removes unused using statements and sorts the remaining using statements in the document being saved.

Clear All Panes
This command clears all output panes. It can be executed from the button on the toolbar of the Output window.

Copy Path
This command copies the full path of the currently selected item to the clipboard. It can be executed by right-clicking one of these nodes in the Solution Explorer:
The solution node; A project node; Any project item node; Any folder.

Email CodeSnippet
To email the lines of text you select in the code editor, right-click anywhere in the editor and then click Email CodeSnippet.

Insert Guid Attribute
This command adds a Guid attribute to a selected class. From the code editor, right-click anywhere within the class definition, then click Insert Guid Attribute.

Show All Files
This command shows the hidden files in all projects displayed in the Solution Explorer when the solution node is selected. It enhances the Show All Files button, which normally shows only the hidden files in the selected project node.

Undo Close
This command reopens a closed document , returning the cursor to its last position. To reopen the most recently closed document, point to the Edit menu, then click Undo Close. Alternately, you can use the CtrlShiftZ shortcut.
To reopen any other recently closed document, point to the View menu, click Other Windows, and then click Undo Close Window. The Undo Close window appears, typically next to the Output window. Double-click any document in the list to reopen it.
