ButtonBar Plus is an enhancement for the Newton 2.1 OS. It adds functionality to the on-screen button bar. New icons can be added to the button bar, and icons can be arranged to the users preferences. The icons can also be shrunk down to half size, allowing twice as many buttons to be available at once.

ButtonBar Plus also gives the users more choices as to how the button bar is displayed. The button bar can be closed, so that it shrinks to a floating window that can be positioned anywhere on the screen. The floating window shows only the basic buttons, leaving the most space as possible free on the screen. ButtonBar Plus also saves button bar configurations, so an individual bars can be set for specific applications.

Button Bar Plus gives you the ability to close the Button bar and use the full screen of your MP2000. Any time you want it open, it's just a tap away and your button bar reappears as a floating palette.
