Apart from a "Process Display Name", processes should have a "Menu Display Name"
The idea is that the process menu (green button on web application) should have the possibility to give the process another name.
It is more intuitive for the end user to click on "New Sales Order" rather than a process called "Sales".
The idea is to make it easy for the end user to select what he wants to start.
You could call the process "New Sales Order" but it doesn't make sense to have this display as the process name since it is so much more than just creating a Sales Order.
Another related issue is that the process name gets copied to the process description and this is very annoying since the menu displays both the process name and description and it just shows duplicated text.
