The PenPoint operating system had novel early implementations of several computing advances, including:
* a large set of [[Gesture recognition|gestures]] such as circle to edit, X to delete, and caret to insert
* using the same gestures at all levels of the operating system and applications
* press and hold for moving any selection, which showed the selection as a floating icon to [[drag and drop]] into a destination
* a rich notebook user [[interface metaphor]]: Documents existed as pages in a notebook with tabs (this was not new in PenPoint, but PenPoint was the first to make it a primary OS interface; Microsoft later did it in [[Windows for Pen Computing]])
* a document architecture where each document was a directory nested in another document's directory (in some sense, this was an extension of the document architecture on [[Multics]])
* dynamic toolkit layout: this allowed applications to rescale for landscape and portrait orientation
* a system-wide pluggable [[address book]]

In April 2008, as part of a larger federal court case,  the gesture features of the Windows/Tablet PC operating system and hardware were found to infringe on a patent by [[GO Corp.]] concerning user interfaces for the PenPoint OS.<ref>{{Cite book
