Right click menu - Remove route - Should have confirm dialog

I was editing a route, and needed to remove a connector. So I right clicked, and there was a "Remove" and "Remove route" menu items. I accidently clicked the "remote route". And the entire route was gone.

I cannot undo this action.

Well you could undo by
1. click source tab
2. cmd-z to undo
3. source code is back
4. click design tab.

But we should add a confirm dialog, when removing an entire route.
