While implementing wirenets, I suddenly needed a dialog box to presnet a tree view of the data. It is especially useful when debugging groups. There are two ways to invoke it: 1. from the Window menu, or {w t} 2. right click on an object and choose context menu item with 'tree' in it A tree view dialog is sheet-specific and there is only one tree view per sheet. When invoked with an object, the tree view navigates to the object within the tree. On the right the there's a preview of the sheet focused on the object the tree cursor is on. The given object should be highlighted in red. At the moment text objects are not rendered (that's a known issue). If the sheet changes, a timer (re)starts and after a period of no change to the sheet the tree is automatically refreshed.
