I like the ContextMenuStrip, I'd forgotten about it too.

Also with the ToolStrip I noticed that the RoundedEdges wasn't working at all when a Preset was selected so I went ahead and fixed it:
Code:
    Public Property RoundedEdges() As Boolean
        Get
            Return _RoundedEdges
        End Get
        Set(ByVal value As Boolean)
            If _RoundedEdges <> value Then
                _RoundedEdges = value
                CType(Me.Renderer, ToolStripProfessionalRenderer).RoundedEdges = _RoundedEdges
                Me.Invalidate()
            End If
        End Set
    End Property
