Live workbooks - being able to be in it at the same time as someone else
It would be great if there was a way for 2 or 3 people to be in a workbook at the same time and see live changes whilst they're happening.
My colleagues and I work near enough solely on Excel and emails due to the line of work we are in. It is very annoying if someone goes in and inputs something and I put in something else or change whatever is already there and it gets over written because the other person saves it before you do or vice versa.
It would be great it this was an option for us to have.
