Hello, First I must say thanks for your efforts on this small tool.
I have some questions regarding to the interface:
1. When I link two nodes, how can I add test on the link? e.g. A have link points to B, I want to mark A is 'depending' on B, but I didn't find a way to add text on the link. I even cannot hightlight the link.
2. Why the often used actions are not supported by toolbar. e.g. add new child, delete, .etc. Right click and choose in menu definitely is not efficient choice.
