From what I read online, it depends on what you use the program for. I think the customization and migration need to improve. Upgrading should be simpler without too many things you need to change or repair. SharePoint Designer should be more practical and become an extension of Visual Studio. Because Visual Studio is a universal development platform. So I don't want to have to switch my user ID every time. So it should be more flexible and more of a mobile app version and integration with other solutions.

Unfortunately Microsoft announced a few years ago that the last update for SharePoint Designer was released on August 2, 2016 and that Microsoft Flow will be the workflow designer and engine going forward. I would add Nintex or all of the Nintex workflow to the solution if I could. I would add them to SharePoint Designer so that I would need to use only one workflow designer. Right now, I'm using SharePoint Designer and Nintex, and it would be better to centralize it.
