It offers very few object shapes; it’s limited to boxes, plain lines, and arrow lines.

Conclusion
I’ve been using your Free Use Case Diagram Tool for a project I’ve been working on, and have stumbled across two issues. The first is that the font used in each diagram is so small it requires me to use something like zoom out or zoom text to make it bearable for reading. The second issue is that the left-hand vertical scroll bar doesn’t work; I need to manually scroll to see all of the diagram.
