User interface with mulitple workspaces
A system comprising:
a display;
first and second workspace data structures relating respectively to first and second workspaces that can be presented on the display; each of the first and second workspaces including a respective set of display objects; each of the display objects being perceptible as a distinct, coherent set of display features; the display objects of each respective set being perceptible as having spatial positions relative to each other when the respective workspace is presented on the display;
display object means for generating first and second display objects; the first workspace data structure being linked to the display object means so that the first display object is in the respective set of display objects of the first workspace; the second workspace data structure being linked to the display object means so that the second display object is in the respective set of display objects of the second workspace; and
control means for accessing the first workspace data structure to cause the display to present the first workspace including the first display object; the control means further being for accessing the second workspace data structure to cause the display to present the second workspace including the second display object; the display object means generating the first and second display objects so that the second display object is perceptible as the same tool as the first display object when the second workspace is presented after the first workspace.
