Some cool new add-ins being bounced around the .NET world this week...
Alex Papadimoulis has a "SmartPaste" add-in that adds the ability to paste text from the clipboard as a region, a string, into comments, etc.
Gaston Milano added some new options to the context menu in VS.NET's file tabs.
Other stuff I've got running:
VSMouseBindings -- Surfing code with the trackbal's back/forward buttons. Solves the problem I posted about last week...
VS Window Manager -- Save/Restore your various window layouts. Especially useful if you go from dual displays to single displays with a laptop.
CodeRush -- It's been a couple of weeks now, but this one deserves its own post.
