The Productivity Power Tools is a super cool pack of extensions that will make Visual Studio 2010 tremendous fun, and make you more productive. Now the team has announced a new version. This lets you turn individual tools on and off, so if you love Highlight Current Line and Go To Definition, but hate Align Assignments, you're in luck:
There's also new tools in the pack. Solution Navigator "merges functionality from Solution Explorer, Class View, Object Browser, Call
Hierarchy, Navigate To, and Find Symbol References into a single view" according to Adrian Collier, and lets you pin tooltips of information near the place in the code where you use them, pops up previews of image files when you hover over them in the tool pane, and just generally reads your mind to make you a happier and more productive developer.
This package had me at "Go To Definition" but these additions make it even more of a must have. You can install right from within Visual Studio 2010, too. Choose Tools, Extension Manager. Click Online Gallery. In the search box type Productivity.
When you see this dialog, click Install:
You'll be prompted to restart Visual Studio:
Click Restart Now and wait a sec. And that's all it takes! You really will love it.
