The interface of Address Plus is very similar to the built in application, so you'll be up to speed with Address Plus in no time. 4 on-screen buttons allow quick selection of the sorting method. The (optional) Letter Bar allows you to quickly jump to your desired record, highlighting the first record that begins with the letter tapped. The Group Edit screen allows you to do Deletes, Category changes, Toggling of Private status, and easily changing the default phone # shown for multiple records all at once.*IMPORTANT NOTE* This version is for Palm OS 3.5 *ONLY*. For earlier versions of Palm OS, try Address+. Also note that the screenshot colors are not accurate for Color Palms.
