Communicate Coughing -- If you try the Communicate Lite demo mentioned in TidBITS #199, and you leave it connected but idle in the background, it will make a slight coughing noise every five minutes to let you know you are still connected, much as AppleLink does. The reminder helps you to avoid running up a phone bill or running down a PowerBook battery. If you don't like the sound, you can turn it off, pick another one, or increase the time between reminders.
Customize Open/Save Dialog Sidebars
You can customize the sidebar in an Open/Save dialog the same way you can in a Finder window: you can reorder the position of items, drag them off into puff-of-smoke oblivion, and even drag a folder from the dialog's list into the sidebar.
