Hi,
I think the ability to have Evident in more than one instance/session should be considered. It helps to not have to back all the way out of a new invoice being input to go search for another invoice or other info, that is related to what you are inputting.
With the new Financial Management Suite you will be able to have multiple windows open. We will soon know what the General Availability date for FMS will be, so stay tuned for that announcement.
