I think we need one more command, which should be very simple to implement: Clear All Breakpoints. Of course we'd love to eventually have a "Manage Breakpoints" view with enabling/disabling/etc. but I don't think we should do that now. We just need the command to enable whenever there are breakpoints and provide a simple Yes/No dialog (that's available from GlobalDisplay) to confirm they want to clear the breakpoints. I don't think this command would need a keyboard shortcut.
