Layer info panel
Layer info panel views some basic statistics of current topic map layer. Exceptionally it doesn't view single topic nor any topic set but number of topics, associations, occurrences etc. in current topic map. Layer info panel is added to Wandora by selecting a menu option View > New panel > Layer info. Next screen capture views Wandora with a Layer info panel. The info panel locates right edge of the window.
Numbers change in the Layer info panel automatically if the user changes topics or associations. To copy numbers into the system clipboard, the user can press the Copy button below numbers. Track changes button is used to freeze base numbers and view additional numbers representing changes (deltas). Layer info panel is useful when the user is uncertain of effects of certain topic map operations. Especially extractors and generators tend to create a lot of topics and associations the user may not notice directly.
