Reb is a PC technician and he wants a piece of software that can show how custom changes can affect the system. Leo says that a Dashboard app is probably the best option. It can read data and then display it graphically. Leo says there used to be an app called Demo that used to do just that. But what Reb is looking for is likely a highly customizable app that he'd need to have written.
Reb could use Excel and Powerpoint together to try it. Other options include SimuL8.com, Visio, and VB. Google Sheets plus Google Data Studio will also work, according to the chatroom. Reb can also check out Work in Progress at barcodestore.co.uk
