Are there any plans to change the configuration software so that you can have more than one configuration open at a time on the same screen? Currently the software will close one configuration before opening another. This makes copying and pasting between configurations more time consuming. It also makes comparing configurations a little more challenging.

You're correct that a single instance of the config tool will not open more than one configuration. However, you can open multiple instances (run the program more than once) of the configuration tool and open other configs that way. Just like how Word works today.
