Visual Studio user settings per project/solution

When working on multiple projects/solutions from different companies or private vs. open source projects, each project can have different language settings (for tab size, curly brace locations, etc.). Keeping these settings at a global (IDE) level forces to constantly switch between global settings and remember which settings file belongs to which project. Allowing these settings to be kept at a solution/project level (in a separate settings file) would allow each project to dicate what its settings are without affecting any other projects.
