Mbeditviz keybinds and new functionalities.

[ESaltPi]

1. Can we get the keybinds that are available in mbedit (r=restore, e=erase, etc.) put into mbeditviz?

2. I also wonder of there can be a new editing option in mbeditviz: Instead of the grab function only doing a rectangle on screen, I think that it would be nice if we could select points by polygon or lasso. In the polygon option, you select corners, and double click to end/close the polygon, and then all points inside are removed. For the lasso, I am imagining a click and drag to select your box. Perhaps in the polygon case, you could shift+click to undo the last corner.

3. Undo: Is there a way of undoing the last erase of points in mbeditviz?

4. In mbeditviz, the grab yellow box appears behind the black dots, which sometimes makes it difficult to tell what you are selecting. Can the yellow box appear in front of the pings?
