A new feature that I really like.
In SW2005, in the configuration specific properties box, you can change to view the properties of another config without getting out & coming back in. Towards the top of the form, look for a list box called Apply to:. As you change the config selected in that list box, the properties below it update to the current config.
You can also highlight a line, as in like you do in Excel, hit CTRL-C to copy it to the clipboard, change to another config with the list box, highlight a line, and hit CTRL-V to paste it in.
