I like that the interface is simple and I don't have to manually drag connectors while still being able to adjust them without too much hassle, but I have not found any tools to optimize the layout of the flowchart. This is a critical omission especially for a tool that markets itself as a brain storming tool because you should be able to create your flowchart without having to ensure everything is in the correct position first. It would also be nice if some additional flowchart symbols get included so that extremely large flowcharts can have off page connectors.
