I also have an issue with the way paths are split. Perhaps I just don't know enough, but the way it keeps going horizontally makes the entire drawing needlessly huge in the horizontal sense. I need it to go vertically eventually.

It's a pretty sleek little app so far, however I have been somewhat unable to format flowcharts the way I want so that they do not become too unwieldy. Adding new boxes and such is not obvious to me, because sometimes SmartDraw decides where the new box will go. This isn't ideal if I have already added text to existing boxes.

This is for work breakdown structures.
