Edit In Place
Designs are hierarchical. That means that in the main design also called top cell references to other cell are placed. In this way repeating structured only need to be created and stored once. With this edit in place feature you are able to edit not only the current cell but also any referred cell without changing the current view. You just set a cell reference as the cell which had to be edited. (e.g by the context menu of the DefaultMode) After doing so all other cell will get a little bit gray and you can easily see which cell you edit. With ToggleDisplaySurround you can even make all other cell invisible.
As a referred cell may be placed twice or more you may edit the top design in more than one location. With MoveCellLeft, MoveCellRight, MoveCellUp, MoveCellDown you can switch through all reference and check whether the editing is correct for all placements.
To end the EditInPlace you can use a Shift+Doubleleft Click in the DefaultMode, the CellUp feature or just the context menu in the DefaultMode
