Make changing weight manually easier.

[radl97]

I have the following problem: if I want to change the weight of an edge, then I have to delete the weight written inside it. This is not a problem at first, but I wanted to try to manually change EVERY edge weight, so I can test what does it do.

You could make changing the weights of the edges easier by some methods:

1. When you click an edge, the program should select the text of the input. After that with one keypress, you can either modify the weight or rewrite it.
2. If the mouse exits the edge, and it goes to the hoverCard, then it shouldn't hide the hoverCard.
3. the input's text is removed when clicking on the edge. This is inferior to point 1, but I don't know how to do point 1.

I support this idea. This would turn to be a nice feature
