Two things which may be nice to add: - adjusting the display for LISA none-square pixels. Scrollbars were about the same size as on the Mac. (A few applications had additional features, like a window splitting widget or dedicated buttons for page wise scrolling, like the Star interface.) - including inactive window states and states for active non-scrolling windows (where the content doesn't exceed the viewport), since there were even more differences in those states and how they were signaling to the user.
