%description
Adds a user-facing undo and redo history to 'Shiny' applications.
Application state, comprising registered inputs and optionally server-side
reactive values, is captured as the user interacts with the application.
Users may then step backwards and forwards through that history with the
keyboard, with buttons, or by scrubbing a visual history rail. Rapid
successive changes, such as dragging a slider, are coalesced into a single
history entry, and related changes may be grouped explicitly into semantic
steps.
