VS 2010 includes new support for better managing debugger breakpoints.  One particularly useful feature is called “Breakpoint Labels” – it enables much better grouping and filtering of breakpoints within a project or across a solution. 

With previous releases of Visual Studio you had to manage each debugger breakpoint as a separate item. Managing each breakpoint separately can be a pain with large projects and for cases when you want to maintain "logical groups" of breakpoints that you turn on/off depending on what you are debugging.  Using the new VS 2010 "breakpoint labeling" feature you can now name these "groups" of breakpoints and manage them as a unit.
