Visual Studio 2010 Productivity Power Tool Extensions

You can download and install the release for free.

Some of the code editor improvements it provides include:

* Entire Line Highlighting: Makes it easier to track cursor location within the editor
* Entire Line Selection: Triple Clicking a line in the code editor now selects the entire line (like with MS Word)
* Code Block Movement: Use Alt+Up/Down Arrow now moves selected code blocks up/down in the editor
* Consistent Tabs vs. Spaces: Ensure consistent tab vs. space usage across your projects
* Colorized Parameters: It is now easier to see/identify method parameters
* Column Guide: You can now add vertical column guidelines to help with text alignment and sizes
* Align assignments: Makes it easier to line-up multiple variable assignments within your code
* HTML Clipboard Support: Copy/paste code from VS into an HTML buffer (useful for blogging!)
* Ctrl + Click Go to Definition: You can now hold down the Ctrl key and click a type to go to its definition

It also includes several tab management improvements for managing document tabs within the IDE:

* Show Close Button in Tab Well: Shows a close button in document well for the active tab (like VS 2008 did)
* Colored Tabs: You can now select the color of each document tab by project or by regex
* Pinned Tabs: Enables you to pin tabs to keep them always visible and available
* Vertical Tabs: You can now show document tabs vertically to fit more tabs than normal
* Remove Tabs by Usage Order: Better behavior when adding new tabs and one needs to be hidden for space reasons
* Sort Tabs by Project: Tabs can be sorted by project they belong to, keeping them grouped together
* Sort Tabs Alphabetically: Tabs can be sorted alphabetically
