Just ran into one of Bill Evjen's blog post about interesting Visual Studio Plugins and from there came across Visual Studio Gallery – Products and Extensions for Visual Studio.
I don't actually mess with my Visual Studio installation (except for CoolCommands) since as we know it's critical for work but if you feel like giving things a test drive then the items there looks pretty interesting. There's just too many new things going on and needs to be learned lately but trying things out than simply reading about them always is a good way to learn.
