One of my favourite extensions in Visual Studio 2012 for the price conscience is Productivity Power Tools 2012.

There are many features which come with Productivity Power Tools 2012 (aka free mini resharper), however one of my favourite features is the new solution wide Remove and Sort.

Remove and Sort is a feature I use constantly on a per class level to remove unwanted using directives and sort them by System first.

Now this can be achieved by right clicking on the solution and then selecting -> remove and sort

Another cool feature is the new Edit Project File as opposed to unload -> edit project file. Quite a minor feature but still worth a mention.
