But, but… really?
Office 2007 is still ubiquitous – surely they've not dropped support for it already? I need to support it, and it seems like this would mean I can't use VS2012.
Or maybe this restriction only applies to the RC? (Please). Or perhaps it creates add-ins that are targetted at 2010 but can still run on 2007? (Clutching at straws).
Tell me it ain't so…
In order to use VSTO you must have Office Installed. The VSTO PIA's only provide a shim between .NET and the COM interfaces that Office exposes. So the PIA's can do nothing w/o Office.
In Visual Studio 2012, open the Options dialog (Tools -> Options). Under Environment -> General, the first setting is "Color theme." You can use this to switch between Light and Dark.
The shell theme is distinct from the editor theme--you can use any editor fonts and colors settings with either shell theme.
There is also a Color Theme Editor extension that can be used to create new themes.

You can create an Office addin that targets 2010, but that still works in Office 2007. The trick is that you need to be aware of what interop types and events are present in 2007 versus 2010. If you try accessing an event or class member that doesn't exist in 2007 you will have issues.
Visual Studio 2012 only includes Office 2010 project templates. Another annoyance/limitation is that they eliminated support of Setup Projects which is how we have been releasing our plugin. Setup Projects have been replaced by InstallShield Limited Edition (ISLE).
