The Action Context and Timeline
Go forward and back the recent history of playpen changes
When in the action context, the context pane has a dynamic ’timeline’ of recent actions, with the most recent first. Any point in that timeline can be selected, and the playpen will be restored as it was then.
Below the timeline is a button for clearing any moves that happened since the last publishing or save of a playpen. When concepts are selected, it clears moves only of selected concepts.
