Enrich VBA, take it out of maintenance mode
So VBA was put into maintenance mode, Microsoft moved programmers to .NET. That was years ago. Office Desktop apps are still selling with VBA and yet VBA has not been enhanced - the two environments do not compete and I have not seen .NET intrinsically replace VBA and packaged as Office's internal programming language. There are so many ways that VBA can be enhanced. Linq can be added so that we are not typing mutiple quotes in unverified statements isolated in a string. String Interpolation. Managing large chunks of text in strings etc.. etc...
